摘要
利用相位编码信号探测高速运动目标时,存在多普勒频率敏感性问题,需要对多普勒频率进行补偿。补偿支路的增加使得运算量和存储量大大增加,为了减少运算量和存储量,提出一种补偿方法,将MTD置于脉冲压缩之前,通过理论推导和Matlab仿真证明了这一算法的正确性与可行性。
When detecting the high-speed moving target by using phase-coded signals, Doppler frequency compensation is necessary because of the Doppler frequency sensitivity of phase-coded signals. A Doppler compensation method is presented in this paper in which the MTD operation is done before pulse compression operation. This method＇s validity and feasibility have been verified in theory and simulations.
