Abstract : We are reporting on a new signal processing technique for the detection of fast accelerating targets that spread over multiple range bins and Doppler filters in the radar receiver. By compensating for these undesirable effects, improvements in coherent gain of more than 2 dB can be achieved, thus optimizing detection performance. The technique is demonstrated with simulated data, and implementation can be expected to be readily feasible with many existing radar systems.
