摘　　要：动目标(MTD)雷达的舰速补偿采用FFT算法的多普勒滤波器组。利用傅立叶变换加权旋转因子的移动,使信号频谱移动量抵消舰速引起的多普勒频率偏移量来实现舰速补偿。当舰速造成动静目标回波频谱太近时,须改变其相参信号实现补偿。applied for The Doppler filter group of FFT arithmetic was velocity compensation is considerable in shipborne radar. The velocity compensation was realized by using the shift character of Fourier Transform that moves the signal spectrum to the travel motion of signal spectrum was counteracted by offset mount of Doppler frequency. The close distance between moving and quiescent target spectrum caused by the moving carrier, Compensation was realized through the coherence signal parameter was changed.
