In this proposal, AlphaSense, Inc. (AI) and the Oklahoma State University (OKState) detail the development of a novel Cavity Enhanced Terahertz Absorption Spectrometer (CETAS). Key innovations of the proposed system include: a) the use of a small Whispering- Gallery- Mode (WGM) cavity to achieve very long pathlength; and b) the integration of the WGM cavity with the conventional pulsed and continu ...

In this proposal, AlphaSense, Inc. (AI) and the University of Michigan (UM) detail the development of a compact, portable, and low cost in-process weld defects detection system. Key innovations of the proposed system include: a) weld defects monitoring based on plasma emission characteristics; b) use the electron temperature of the plasma as an indicator of the weld quality, c) use multiple plasma ...

Problem UAVs hold great potential for force multiplication and increased functionality. To deliver on this potential, future UAV systems must include reliable and flexible autonomous control. UAV autonomy is limited. The desireable level of autonomy depends on many factors. Ideally, the level is dynamic, raising and lowering in response to the mission phase and realworld contingencies. ...

Ballistic missiles pose formidable challenges for target tracking and intercept because of their spiraling dynamics and significant maneuverability potential as they re-enter the atmosphere at high speeds. Recent studies have shown that conventional methods to estimation, guidance and control design are unable to guarantee sufficient accuracy against such highly maneuvering targets. This is not un ...

PRA proposes to develop a wideband adaptive digital beamforming solution to autonomously cancel multiple jammers at various locations, bandwidths, and center frequencies. The wide waveform bandwidths desired for fine range resolution in current and future phased-array systems impact the performance of adaptive cancellation algorithms due to the effects of wideband jammer dispersion, antenna archi ...

A simple clamping U bracket to secure itself under pressure on both sides of the aircraft's structural frame ribs. A clamp will be placed on every section where the bonded studs currently exist. A cavity on the bottom of each clamp will hold a stud or other tool to secure the blankets. The outer surface of the bracket will be made of rubber and the inner core will be made of 9255 spring steel, ...

nGimat proposes to develop a phased array antenna on lightweight substrates, consisting of ferroelectric phase shifters, feed network, and radiating element. The array antenna will be electronically scanned, eliminating mechanical problems of a rotating array. In Phase I, we will design a phased array antenna with reconfigurable elements, design and fabricate phase shifters, and work with our in ...

Accurate numerical predictions of antenna performance on aircraft are important in many problems of avionics design and integration. In particular, such predictions are needed to determine optimal antenna placement on aircraft in order to achieve required coverage. The focus of this project is an investigation and development of new high-frequency computational methods and codes for accurate and e ...

The nature of electromagnetic launchers requires operation in a harsh environment due to the large electromagnetic field, electrical current, temperature, and mechanical stresses present during a shot. This environment can significantly reduce the lifetime of the rails and therefore limits the military utility of the device. Increasing the lifetime of the rails while maintaining high launch velo ...

The DoD STTR solicitation is seeking to identify innovative technology to provide a quantum leap in performance for cryocooler systems. Successful development of such an innovative technology will result in lowering the cost and risk of cryocoolers while increasing reliability and lifetime, which will lead to increased producibility of cryocooler systems. Johnson Research & Development Co., Inc. ...
