This task involves research and theoretical analyses concerning the development of new techniques and radar system concepts (spatially and spectrally diverse radars), which provide greatly improved performance for ground, air, and space surveillance (passive and active) radars; synthetic aperture (and “all target” imaging) radars; sparse arrays; multi-static radar; distributed RF sensors; and multiple aperture interferometric radars. Current topics include suppression of range-angle-Doppler ambiguities, analysis of ambiguity induced limitations from an information theoretic viewpoint, interferometric clutter cancellation and interferometric height discrimination, automatic focusing, preprocessing for clutter and electromagnetic interference suppression prior to space-time adaptive processing, and multifrequency waveform diverse radars for persistent surveillance combined with high fidelity imaging and feature extraction for processing, exploitation and dissemination (PED). Extensive computer modeling, simulation facilities, and experimental data sets are available to support this research.
