Army missions require robust, error-free transmission of video data without network errors. In compressed data, such as with H.264 or H.265 compressors, small bit errors can obliterate large portions of the de-compressed image, or render it un-compressible at all, depending upon where in the compressed data the errors occur. Dropped packets may obliterate frames containing significant mission-crit ...

US warfighter safety could be significantly improved by providing an ability to quickly and accurately assess the acoustic impact of rotorcraft operations in the field and reduce the likelihood of detection. Current mission planning tools are empirical in nature, limited to operating conditions for which flight test data exists and challenged in predicting the acoustic impact of maneuvering flight ...

The repair and rebuilding of injection molded parts is an important activity at army depots. The unit cost to make small batch parts is quite expensive due to the high cost and long lead time for injection molds for tooling. Fused Filament Fabrication AM offers a viable alternative to reduce tooling costs and lead time, however most AM thermoplastics do not meet the stringent requirements of high- ...

Opioids are a class of potent analgesics used for both pain relief and their euphoric effects. The range of effective doses stretches across multiple orders of magnitude, down to micrograms per individual for a lethal dose. With such low doses causing significant intoxication, it is crucial to identify novel markers and means to monitor for opioid exposure both on the battlefield (opioid chemical ...

The nature of complex combat operations must now include adversaries that have peer-level capabilities, such as the ability to locate friendly troops by their transmissions and jam their radios so they can’t call for help, setting them up for attack. However, critical to all combat scenarios, regardless of adversary capability levels, is the need to command, control, communicate and exchange inf ...

The objective of this proposal is to enable high-sensitivity, passive imaging system of natural mm-wave emissions, which can be used as standalone or fused with other imaging modality such as conventional IR imagery in degraded environments. This is achieved through a unique antenna integrated electro-optic (EO) modulator, where received mm-wave signals modulate an optical carrier. The optical car ...

To date, Simultaneous Transmit and Receive (STAR) solutions have primarily relied on a circulator in the RF frontend, paired with digital signal processing (DSP) to suppress the approximately known transmitted signal. These techniques have demonstrated only limited isolation and bandwidth and struggle to remove non-linear harmonics and transmit noise. Moreover, the limited isolation of circulators ...

To meet the demands of topic A19-009, the MaXentric team proposes the MAESTRO (Millimeter-wave Amplifier under Efficient Switching-mode and Time-multiplexing Operations), which provides a new concept of a power amplifier in millimeter-wave frequency band for commercial and military communication and electronic warfare applications. Using time-multiplexing technique and switching-mode amplifier, hi ...

A major innovative thrust in Army tactical operations is routine use of small Group 1 UAS for surveillance and sensing missions. However, for effective and stealthy use of such assets, low acoustic signature is critical. At present, capabilities for designing such vehicles for minimum noise is extremely limited, especially when combined with the challenge of designing to meet critical mission requ ...

Rotorcraft, both civilian and military, suffer from higher operating costs relative to their fixed-wing brethren due to cyclical loading that limits the useful lifetime of key structural components. Important recent advances in aeromechanics prediction capabilities, coupled with enhanced modeling of fatigue growth on life-limited parts, now allows development of a methodology both to predict real- ...
