Time-Range Adaptive Processing for pulse agile radar

Some radar systems utilize pulse agility to mitigate interference or synthesize bandwidth. Transmitting different waveforms on a pulse-to-pulse basis can have deleterious effects when traditional pulse-Doppler processing is employed. In this paper a recursive MMSE-based receiver design, denoted as Time-Range Adaptive Processing, is presented. The new method jointly adapts in range and Doppler, thus yielding enhanced sensitivity when compared to adaptation in each dimension separately.
