A target angle estimation technique making effective use of the spatial degrees of freedom of an adaptive array radar system has been developed by ASI and demonstrated to yield unbiased and efficient angle estimates in near-main beam jammer environments. The program objective of progressing towards a feasibility demonstration includes optimizing system designs including the detection and post-dete ...

Development of advanced diagnostic techniques and spray characterization methodologies are essential to the understanding of the complex spray process and for validating state-of-the-art CFD codes that are available for describing the spray process. Novel diagnostic techniques and measurement schemes have been proposed for evaluation in this proposal. The application of the well-established phase ...

Reconnaissance and surveillance missions, using small robust spacecraft, may require that sensors be rapidly positioned to suit the specific mission requirements. These maneuvers are most effectively conducted using a CMG with an output torque of 2-100 ft.-lbs.; however, the smallest CMG currently available has an output torque that is 225 ft.-lbs. and has a weight of 112 lbs. In order to meet the ...

An innovative and cost-effective approach is proposed for site survey and detection of buried ordnance. The technique is based on development of a "ground penetrating radar" (GPR) and associated multitask software control package. This system can be used to generate, transmit into the ground, and receive step frequency electromagnetic signals with ability to control the frequency number. Algorithm ...

There is significant interest in the use of net-shape processing to fabricate heavy metals to circumvent the problems of strain hardening and high cost issues related to machining. Ceracon has demonstrated the feasibility of forming tantalum plates having ultrafine grained microstructure, which exhibits isotropic mechanical behavior at low and high strain rates, and a significantly higher static s ...

Sub-beamwidth resolution technique achieving active target imaging for final aim-point selection at 94 GHz is proposed for smart munition sensor applications. Based on focal plane array concept and with sub-beamwidth resolution software development, our proposed innovative approach combining with a high range resolution FMCW waveform sensor hardware already developed by CHANG is expected to greatl ...

Diamond films grown by plasma enhanced chemical vapor deposition (CVD) have become an important engineering material. Microwave plasma (MP) CVD ofdiamond is particularly advantageous because it leads to material with the highest quality in terms of impurity content, electronic and optical properties, and carries fewer liabilities of power inefficiency and excess heat removal than other deposition ...

The goal of this effort is a family of adaptive passive damping elements that will improve performance, endurance and survivability of future advanced space and missile systems. The innovation is twofold: the damping elements will be advanced tuned-mass dampers (TMDs) that (1) use magnetically induced eddy currents as the dissipation mechanism and (2) have an adaptive frequency tuning scheme. As t ...

There is a need for COmpai-t, efficient blue lasers to enable expansion of current applications into b^roader markets. For example, the demand for molecular sequencing instruments is expanding from research into clinical applications, but a small, relLable laser source is needed to meet the re- quirements of this new market. Several approaches have been demonstrated by us and others for efficientl ...
