摘　　要：提出了一种脉冲群间多普勒频率变化率估计算法,该算法利用离散傅里叶变换进行脉冲间相参积累,获得脉冲群的相对模糊频率,通过脉冲群间相对模糊频率差分获得多普勒频率变化率。算法具有计算量小、多普勒频率变化率估计精度高的优点。计算机仿真结果证明了算法的有效性。In this paper,an estimation algorithm for doppler frequency rate-of-change between the pulse groups is proposed.DFT(Discrete Fourier Transform) is used to realize coherent integration between the pulses and obtain the relative ambiguous frequency of pulse group.Doppler frequency rate-of-change is estimated in terms of difference of relative ambiguous frequency of the pulse groups.This algorithm has small computation amount load and has high estimation precision of doppler frequency rata-of-change.The effect...
