Nuclear Radiation Detecting Device Could Produce New Homeland Security Tool

A Northwestern University and Argonne National Laboratory research team has developed an exceptional next-generation material for nuclear radiation detection that could provide a significantly less expensive alternative to the detectors now in commercial use. Specifically, the high-performance material is used in a device that can detect gamma rays, weak signals given off by nuclear materials, and can easily identify individual radioactive isotopes. It has been more than 30 years since a material with this performance was developed, with the new material having the advantage of inexpensive production.

Navy Researchers Work to Lighten, Strengthen Warfighter Armor

A multi-disciplinary team of researchers at the U.S. Naval Research Laboratory pushed grain size engineering to the limit and recently discovered previously unseen behaviors in nanocrystalline ceramics that could lead to the design of better performing ceramic armor. The discovery, a continuation of NRL research published in 2014, was made possible by a cutting-edge nanosintering technique, which is the process of essentially bonding nano-sized particles together.

New Products: May 2018 Aerospace & Defense Technology

Rapid Deployment SIGINT Sensor

VStar Systems (San Diego, CA) announced the addition of a pod version of its MA-C SIGINT Sensor, the MA-C MiniPod™. Two active high frequency (HF) antennas allow for intercept and copy of land mobile radios from both direct Line of Sight (LOS) as well as Near Vertical Incidence Skywave (NVIS) signals for Beyond Line of Sight (BLOS) communication methods. The MA-C MiniPOD can be installed on most standard airborne racks/missile launchers for integration on a wide variety of platforms.

New Technologies Tackle UAV Challenges

Unmanned vehicles for air, land, and water represent an increasingly-important capability for virtually all military services worldwide. Because each new generation of device technology promises capabilities and higher levels of overall performance for unmanned vehicles of all types, military customers expect these benefits in the latest UAV offerings. To meet these expectations, systems engineers must deal with increasingly difficult problems of thermal management, power budgeting, EMI emissions and susceptibility, weight, size, cabling, connectors, antenna management, and command/control functions. Several new technologies and innovative packaging concepts now provide better solutions to these issues.

Robotic Applique Kits Leverage Existing Assets

When it comes to modern military operations, robotic technology provides a tremendous tactical advantage. Drones, ground robots and autonomous vehicles are routinely used for missions such as intelligence-gathering, surveillance and reconnaissance (ISR), allowing military personnel to conduct operations from a safe distance. And yet, despite these technological advances, the vast majority of vehicles in use by the military — whether in the air or on land — still require a human operator.

Protecting Critical Data on Unmanned Underwater Platforms

Emerging mission requirements from global defense forces are driving new programs and applications for Unmanned Underwater Vehicle (UUV) platforms. Like their airborne counterparts, UUVs are ideal for deploying Intelligence, Surveillance and Reconnaissance (ISR) mission payloads. To speed the development of these autonomous vehicles, system designers are turning to small form factor (SFF) Commercial off the Shelf (COTS) technologies previously proven in Unmanned Aerial System (UAS) deployments. These low-power SFF subsystems, including miniature network switches and mission computers, are ideal for use in UUVs for which any additional weight or power consumption can have significant detrimental effects on mission distance and duration. By selecting proven rugged COTS solutions, already tested and qualified to the extreme demands of MIL-STD-810G, MIL-STD-461, MIL-STD-704 and/ or RTCA/DO-160G standards for environmental, power, and EMI compliance, UUV system developers have found that they can greatly accelerate their program integration and reduce overall risk.

Educating UGVs

Advancements in the field of artificial intelligence (AI) are accelerating as the technology matures from being research-orientated to being deployed in a wide range of products and services, such as autonomous vehicles. While Convolutional Neural Networks (CNNs) were first described in the 1950s, the technology remained an academic concept until the availability of large training data sets and powerful Graphics Processor Units (GPUs), a processor architecture ideal for the heavy math computational demands associated with neural network processing. Once scientists had low-cost and high-performance platforms, the technology exploded for many commercial uses. Military use is more challenging due to the lack of large data sets, but that is changing too as areas including thermal imagery are starting to be used.
