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 ...

BESOI fabrication techniques will be evaluated to select an optimum approach for manufacturing ultrathin silicon films on 150- and 200-mm diameter wafers. A supplier of such BESOI material will be identified. The baseline will be the SiGe etch stop and strain-sensitive etch method which ARACOR has already demonstrated to be capable of producing defect-free, undoped films that are as thin as 1000 a ...

The Discrete Wavelet Transform (DWT) is a Time-Frequency Distribution (TFD) which offers the potential to efficiently characterize both transient and global intrapulse signal features in a highly compressed format. The overall objective of this three phase effort is to develop Wavelet analysis as a new approach to modulation on pulse (MOP) processing in support of electronic warfare (EW) systems i ...

The proposed program utilizes advanced radar technology to develop a fuze for penetrating weapons. The technology is the result of Aeres efforts in the analysis and design of Ground Penetrating Radars. The unique approach utilizes millimeter-sized impulse diodes to develop extremely short microwave pulses, and digital processing to characterize the return signal. A test program will provide dat ...

The objective of this project is to implement and demonstrate a comprehensive physical model and practical computation tool for predicting/analyzing soot formation due to hydrocarbon-fuel combustion is liquid-propellant rockets. A state-of-science approach is proposed for understanding/ quantifying soot formation mechanisms/rates and for investigating/ designing methods to minimize the mass/numbe ...

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 ...

A real-time non-intrusive turbine engine exhaust particulate monitor, based on simultaneous multi-wavelength backscattering and extinction measurements, has been proposed herein. The objective is to mathematically invert the simultaneously measured laser light extinction and light scattering at different wavelengths to yield accurate and reliable reconstruction of the particle size distribution. T ...

Current lithography techniques generally adopted by the semiconductor industry in the U.S. and other nations involve the use of masks which are prepared either by photolithography or by electron beam lithography. The masks consist of a glass plate on which a layer of chrome and another layer of resist are deposited. The resist is developed where it is irradiated and the chrome is etched thus leav ...
