The Global Positioning System (GPS) has revolutionized military operations by providing global access to high-quality position, navigation, and time (PNT) data. Along with the rise in GPS usage has been a parallel increase in threats to GPS data availability. GPS signals are easily jammed due to their low signal power and fixed frequency of operation. Spoofing attacks threaten military systems bei ...

Today’s warfighter is often called upon to operate in extremely cold environments, both in operational and training settings. These environments can range from operating or training in geographical or seasonally cold areas to performing a high altitude, high opening (HAHO) or high altitude, low opening (HALO) parachute jump in extremely cold ambient temperatures. To operate in these environments ...

Emerging missile threats to Army assets often fly through and maneuver at higher altitudes. In addition, Army interceptors launch from the ground and will likewise need to fly through / maneuver at higher altitudes to engage such threats. The associated changes in flight conditions cause threat and interceptor signatures to change substantially from those usually observed by Army sensors and seeke ...

A CONTROLLED RELEASE ANTIBIOTIC WOUND DRESSING IS TO BE DEVELOPED FOR ADMINISTRATION OF BACITRACIN AND POLYMIX B. THE DRESSING IS TO BE EASILY APPLIED AND CONFORMABLE TO WOUND SURFACES. BOTH ANTIBIOTICS ARE TO BE MAINTAINED AT EFFECTIVE LEVELS WITHIN WOULDS FOR THREE DAYS, PREVENTING INFECTION FOR THIS PERIOD OF TIME. THE DRESSING IS TO BE INCORPORATED INTO POROPLASTIC CELLULOSE TRIACETATE MEMBRAN ...

Logistic operations for all branches of the military have historically been a guessing game relying on the intuition and past experience of the responsible officials. Unfortunately, this strategy often means that resources are deployed prematurely to areas that do not have an immediate need, thereby denying those assets to other areas that could have used them immediately. Worse, resources can als ...

GENERATOR USED PRIMARY POWER SYSTEMS ARE THE ACHILLES HEEL OF TACTICAL COMMAND AND CONTROL SYSTEMS, FIELD HOSPITALS, AND OTHER TACTICAL SUPPORT FACILITIES. THEY ARE NOISY AND PRONE TO FAILURE AT THE MOST CRITICAL TIMES. TACTICAL POWER USING SYSTEMS HAVE DIFFERENT POWER DUTY CYCLES AND POWER FACTORS. SOME ARE PREDICTABLE; OTHER TOTALLY RANDOM; AND MANY MUST BE DEPENDED UPON IN THE "HEAT OF THE BATT ...

SCOPE PROPOSES TO DEVELOP A DIGITAL SIGNAL PROCESSING CONCEPT FOR THE REALTIME DETECTION AND IDENTIFICATION OF HF EMITTERS AND THEIR PLATFORMS. THIS INVESTIGATION WILL SPECIFICALLY EVALUATE HF EMITTER CHARACTERISTICS AND PHENOMENA OF POTENTIAL INTEREST FOR IDENTIFICATION. SIGNAL PROCESSING TECHNIQUES AND ALGORITHMS WILL BE DEFINED TO EXPLOIT EMITTER AND PLATFORM IDENTIFIABLE SIGNAL CHARACTERISTICS ...

The objective of this program is to achieve direct analog-to-digital conversion of microwave signals with high resolution, using hardware that is universally applicable to a wide range of systems. (This is also referred to as digital downconversion or direct RF sampling.) Doing so will eliminate all analog downconversion stages and will reduce the analog front end of a radar receiver to a single f ...

Many emerging industry and military applications require high power, high brightness laser systems with greatly reduced size, weight, and power consumption (SWaP) so that they can be integrated into a compact and mobile platform. Current High Energy Laser (HEL) weapon systems are mainly based on spectrally beam combined fiber laser technologies, which enable high output power levels but suffer fro ...
