摘要
Abstract
During the flying course of a spinning target, the receiving signal will be modulated by micro-Doppler. Through theoretical and simulative analysis of the cooperative target which usually transmits by transponder,it is found that the eclipsing effect in the signal transmission mode with double-antenna will af-fect the micro-Doppler modulation of receiving signal. The relationship between the relative position of tran-sponder antenna and the phase characteristics of micro-Doppler is analyzed by modeling the micro-Doppler model of cooperative target. The modulation signatures of micro-Doppler of the receiving signal are deduced in double-antenna condition and the receiving signal model with corresponding time-frequency feature is given. Then the intermittency of the measured signal caused by the switch of antenna is discussed. Finally, the next viable signal processing methods are presented according to the time-frequency feature.关键词
