Consolidation Is 
the Course for Army 
Electronic Warfare

April 1, 2013
By Robert K. Ackerman

Melding the disciplines of spectrum combat will enable greater flexibility and more capabilities.

The growth in battlefield electronics has spurred a corresponding growth in electronic warfare. In the same manner that innovative technologies have spawned new capabilities, electronic warfare is becoming more complex as planners look to incorporate new systems into the battlespace.

No longer can electronic warfare (EW) function exclusively in its own domain. The growth of cyber operations has led to an overlap into traditional EW areas. EW activities for countering remote-controlled improvised explosive devices (IEDs) in Southwest Asia led to an increased emphasis on EW defense and offense. It also exposed the problem of signal fratricide when those EW operations interfered with allied communication.

The U.S. Army sped many systems into theater, and now it is working to coordinate those technologies into a more organized capability. The effort focuses on an integrated EW approach that will reconcile many of the existing conflicts and clear the way for more widespread use of EW in future conflicts.

“The Army definitely has wrapped its arms around the importance of EW,” declares Col. Joe DuPont, USA, project manager for electronic warfare at the Program Executive Office (PEO) Intelligence Electronic Warfare and Sensors (IEWS), Aberdeen Proving Ground, Maryland.

The majority of the Army’s EW assets currently come from quick reaction capabilities (QRCs) that have been fielded over the past decade; these capabilities are attack, support and protection. The requirements largely came from theater, and the next systems due for fielding reflect those requests.

Marines Research 
Modernization

April 1, 2013
By Rita Boland

Looking past the alligators close to the boat, scientists prepare for the wars of tomorrow.

Distributed operations are the future of the U.S. Marine Corps, and its premier science and technology organization is laser focused on the capabilities to make such missions a success. Enabling communications for mobile troops across long distances is a priority as battles continue in Afghanistan while the focus shifts toward more maritime environments. Success will give lower echelons better access to command and control, enhancing the fight in any theater.

Brig. Gen. Mark R. Wise, USMC, commander of the Marine Corps Warfighting Laboratory (MCWL) and vice chief of naval research, explains that people usually think of modernizing a force as working on resources to be ready in five to 10 years, but efforts at the laboratory reach much further ahead. “We are influencing the very leading edge,” he states. The research helps define what times to come should look like for Marines and what they will need to operate effectively. This aim at the future influences the requirements that influence modernization.

“The MCWL is very focused on distributed operations right now,” Gen. Wise explains. Units in current conflicts already operate at great distances from other units or their own command and control (C2) elements. As operations shift to the Asia-Pacific, such distance problems are likely to increase. The MCWL is working on methods to sustain—through enhanced logistics—and command and control such a force. Researchers are exploring material and nonmaterial solutions to find the correct enabling capabilities.

One Small Step
 Toward Greater
 Interoperability

April 1, 2013

An upcoming demonstration could lead to a giant leap in common electromagnetic components.

U.S. Army researchers intend to demonstrate in the coming weeks that some components, such as antennas and amplifiers, can perform two functions—communications and electronic warfare. The ultimate goal is to use the same components for multiple purposes while dramatically reducing size, weight, power consumption and costs. The effort could lead to a set of common components for electromagnetic systems across the Army, the other military services and even international partners, which would be a boon for battlefield interoperability.

Researchers at the Army’s Communications-Electronics Research, Development and Engineering Center (CERDEC), Aberdeen Proving Ground, Maryland, are discussing the concept with personnel from a wide range of organizations, including the Army Research Laboratory, the Defense Advanced Research Projects Agency, Navy and Air Force research laboratories, universities and other countries. The idea is for common components for command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) to serve multiple functions, such as communications and electronic warfare, possibly switching from one function to the other or even conducting multiple missions simultaneously.

“We work with a number of international partners—NATO of course,” points out Paul Zablocky, senior research scientist for electronic warfare within CERDEC’s Intelligence and Information Warfare Directorate. “The other one is The Technical Cooperation Program, which is called TTCP. That particular organization covers the United Kingdom, Australia, New Zealand, Canada and the United States.”

Sandia Starts Multiple High-Tech Projects with Caterpillar

Sandia National Laboratories has signed an umbrella Cooperative Research and Development Agreement (CRADA) with Caterpillar Incorporated that covers multiple projects over the next three years. Though Caterpillar is best known for large construction and mining equipment, the CRADA authorizes work in computer and computational science, information and data analysis, mathematics, engineering science and high-performance computing. Technical categories covered by the agreement include simulation design exploration, advanced analytics, multiphysics engineering modeling and simulation, and high-performance computing. Caterpillar is seeking help from Sandia to develop advanced modeling and simulation technologies for virtual product development. Sandia has several technology partnership options that industry, nonprofits, government and academia can use to access the laboratories’ resources.

Researchers Develop Technology for Tailor-Made, Multipurpose Robotics

March 25, 2013
By George I. Seffers

Scientists at the Massachusetts Institute of Technology (MIT), Cambridge, are continuing to develop a robotic technology that can transform into a virtually infinite number of shapes. In fact, the breakthrough has led to some surprising spin-off projects, including research into aircraft control actuators and medical devices.

MIT first announced the caterpillar-size device last November after the original effort, which was funded by the Defense Advanced Research Projects Agency (DARPA), was completed. The original Programmable Matter project resulted in a device called a milli-motein, a name inspired by its millimeter-size components and a motorized design resembling proteins that fold themselves into complex shapes.

The technology could one day allow warfighters to design and build robotic systems on the fly to meet specific challenges—maneuvering through the space inside walls to gather reconnaissance information, for example. Now, the technology is being further developed in another DARPA project, the Maximum Mobility and Manipulation program, which seeks to improve the capability of robots to traverse tough terrain and to grasp or manipulate objects. “What our group has been doing is looking at how to apply our technologies for building structures from digital composite technology,” reports Ara Knaian, a visiting scientist at MIT, who helped design the unique electro-permanent motor that drives the milli-motein technology.

Increasing Machines’ Learning Curve

March 21, 2013

The Defense Advanced Research Projects Agency (DARPA) is searching for companies to participate in its recently launched Probabilistic Programming for Advanced Machine Learning (PPAML) program. Probabilistic programming is an innovative approach to manage the uncertain information that computers use to understand data, manage results and infer insights. The PPAML seeks to increase the number of people who can successfully build machine learning applications as well as boost the effectiveness of current machine learning experts. In addition, the project will focus on creating more economical, robust and powerful applications that require less data to produce more accurate results. “Our goal is that future machine learning projects won’t require people to know everything about both the domain of interest and machine learning to build useful machine learning applications,” Kathleen Fisher, DARPA program manager, says. The three-phase program is scheduled to run for 46 months beginning this year and continuing to 2017. The agency is hosting a Proposers’ Day at the Executive Conference Center, Arlington, Virginia, on April 10, 2013, to familiarize potential participants with the PPAML’s technical objectives. Interested organizations must register by 5 p.m. on April 5, 2013. A DARPA special notice document describing the specific capabilities the agency is interested in is available online.

 

NASA Tests Biofuels for Environmental Effects, Performance

March 15, 2013

NASA is in the midst of its first phase of flight tests to determine the effects of alternative biofuels on the emissions and performance of jet engines flying at altitude.

The program is called the Alternative Fuel Effects on Contrails and Cruise Emissions, or ACCESS, according to Dr. Ruben Del Rosario, project manager of NASA’s Subsonic Fixed Wing project. The goal is to investigate how biofuels perform compared with traditional jet fuel and also to measure the environmental impact of biofuels. The results of the tests are significant because of the growing popularity of biofuels for both the U.S. Air Force and Navy as well as private sector aviation.

During the ACCESS tests, the space agency’s highly modified Douglas DC-8, which normally is used as a flying laboratory, will conduct a series of flights at altitudes as high as 40,000 feet, while a NASA Falcon HU-25 aircraft follows behind at distances of between 300 feet and more than 10 miles, according to Del Rosario. The flights will take place primarily over restricted airspace over Edwards Air Force Base in California.

ACCESS is the outgrowth of earlier preliminary research on biofuels and jets. “It was born out of two previous experiments that we conducted in 2009 and 2011 at NASA’s Dryden Aircraft Operations Facility,” Del Rosario explains. During those tests, ground-based instruments measured the exhaust emissions of the DC-8 while the plane was parked on a ramp at the Palmdale, California, facility.

“During the ground tests, we took very detailed emission measurements, measuring CO2 [carbon dioxide], different oxides, different particulates, measuring sulfur, all the different kind of emissions we could possibly measure with many other companies and institutions joining us, as well,” Del Rosario says.

A New Chip Thinks Like a Brain

An Army research team develops a device that could assist warfighters' decision making.

A U.S. Army scientist and his colleagues, working in the nascent field of neural computing and quantum physics, have earned a patent for a powerful quantum neural dynamics computer chip. The device, which has been tested in a laboratory, and the advanced mathematical computations that make it work may lead one day to powerful devices that could help warfighters sift through huge datasets of information and make important tactical decisions in the field. The chip also holds promise for civilian applications requiring the rapid analysis of big data, and it could represent a bridge to the next generation of computing.

“The patent covers different ways to make computer chips,” states Ron Meyers, a computer scientist with the Army Research Laboratory (ARL) who is the principal investigator for the neural chip project. “We developed a type of mathematics that allows for quick function-changing and also emulates some of the processes of neural intelligence that the human brain uses. We combined those together, and we made a new type of computer chip that incorporates those functions. It’s qualitatively different. It doesn’t do the same kinds of computations as traditional computer chips.”

The chip, and its underlying operating system based on newly developed mathematical formulas, will make possible faster and more powerful computers. “We’re talking about the ability to compute that exceeds exponentially millions of times greater than any of the computers that exist today or are on the drawing boards using conventional approaches,” Meyers explains.

When it comes to popular smartphones and tablets, security can be a many-layered and necessary endeavor

The growing use of advanced mobile devices, coupled with the increase in wireless broadband speed, is fueling demand by employees to bring their own devices to the job. This situation has opened a new set of security challenges for information technology staff, especially when it comes to the use of apps.

As the popularity and capability of mobile devices expands, standards are necessary to ensure that personal devices can function securely on enterprise networks. To address this need, the Cloud Security Alliance (CSA) organized its Mobile Working Group last year. The group recently released guidance to members on how enterprise administrators can successfully integrate smartphones and tablets into their work environment. The CSA is a not-for-profit organization of industry representatives focused on information assurance in the cloud computing industry.

Two-in-One Unmanned Aircraft

U.S. Navy technology may allow in-flight conversion from helicopter to fixed wing.

Researchers at the U.S. Naval Research Laboratory are developing unmanned aircraft technology that will allow the conversion from a vertical take-off and landing system to a fixed-wing craft during in-flight operation. The conversion capability will provide the take-off and landing flexibility of a helicopter with the longer range, higher speeds and lower wear and tear of an airplane.

The technology demonstrator is referred to as the Stop-Rotor Rotary Wing Aircraft. It is capable of cruising at about 100 knots, weighs less than 100 pounds and can carry a 25-pound intelligence, surveillance and reconnaissance (ISR) or electronic warfare payload, such as the Expendable, Mobile Anti-submarine warfare Training Target (EMATT). “We decided to do a demonstration vehicle that could carry an EMATT. It’s like a little submarine that can generate sonar signals, and it’s for training anti-submarine warfare operators,” explains Steven Tayman, an aerospace engineer at the Naval Research Laboratory. “It’s a neat payload.”

The unmanned aerial vehicle (UAV) includes a removable payload bay that is about 12 inches wide, 38 inches long and six inches deep with “bomb bay doors” for dropping payloads, such as sonobuoys. “You could use a UAV to deploy a sonobuoy field, which would be pretty exciting,” Tayman says. “There’s really no limit to the payload other than volume.”
