Abstract :
We developed a constant false alarm rate (CFAR) strategy for detecting the blade echo-signal of a hovering helicopter with phased array airborne early warning (AEW) radar, which is based on the time-space cascaded adaptive processing approach (TSA) and "multi-Doppler channels joint detection" technique. The configuration of detector is given, the performance of the detector is analyzed, and the feasibility and effectiveness are verified with computer simulations
