Rapidly Adaptive Intelligent Radar (RAIR)

The sample support problem in space-time adaptive processing (STAP arises from the requirement to adapt to a changing interference environment where the available wide-sense-stationary sample support is severely limited for direct implementation ofadaptive algorithms. In this proposal by combining several approaches such as (i) forward/backward subaperture-subarray smoothing techniques (ii) alternating projection algorithms using relaxed projection operators, and (iii) optimum transmitter-receiverdesign, we have shown that it is possible to reduce significantly the data support in nonstationary environments and achieve superior performance. During the Phase II work period, C & P Technologies proposes to design and build a toolbox called
