主 题:ground moving target indication(GMTI) space-time adaptive processing(STAP) amplitude and phase estimation(APES) clutter.
摘 要:Space-time adaptive processing(STAP) has been proven to be one of the best techniques capable of detecting weak moving targets in strong clutter environment and has been widely applied in airborne ground moving target indication(GMTI) *** paper applies an amplitude and phase estimation(APES) approach to two aspects of the STAP ***,APES is applied to accurately describe the clutter characteristic in angle-Doppler ***,APES is incorporated into the standard STAP algorithm to improve its performance without increasing transmitting/receiving channel and pulse *** experimental examples show that the detection performance can be improved by using the APES technique,as well as the high computational complexity can be avoided.
