摘　　要：对基于FFT频谱分析技术的连续波雷达，在大加速度情况下，频谱的展宽使连续波雷达的测速精度降低。针对加速度补偿问题，分析加速度引起的频谱展宽问题，介绍了1种基于离散相位变换（DPT）技术的加速度补偿算法，讨论了算法的原理和运算量，并对算法进行仿真。实验结果表明，采用该算法进行加速度补偿能有效提高连续波雷达的测速精度。In the case of large acceleration, the spectrum broadening reduces the speed measurement accuracy of the continuous wave radar based on frequency spectrum analysis. For acceleration compensation, the paper first analyzes the spectrum broadening problem caused by the acceleration, an acceleration compensation algorithm based on discrete phase transformation （DPT） is introduced, its principles and computional costs are discussed in details. The experimental results show that the acceleration compensation algorithm can effectively improve the speed measurement accuracy of continuous wave radar through simulation.
