RT_STAP: Real-Time Space-Time Adaptive Processing Benchmark

Abstract : This report provides a specification of the RT_STAP benchmark for evaluating the application of scalable high performance computers to the real-time implementation of space-time adaptive processing (STAP) techniques on embedded platforms. STAP is an adaptive processing technique used to support clutter and interference cancellation in airborne radars. The RT_STAP benchmark is an example of a compact application benchmark that uses a real time design-to-specification methodology. The scalability study outlined in the RT_STAP benchmark varies the sophistication and computational complexity of the adaptive algorithms to be implemented. The benchmark provides hard, medium, and easy benchmark cases based upon three post-Doppler adaptive processing algorithms: higher-order Doppler-factored STAP, first-order Doppler-factored STAP, and post-Doppler adaptive Displaced Phase Center Antenna (CDPCA).
