摘　　要：为解决PRI抖动信号的分选问题,提出了一种基于累积方正弦波插值的信号分选方法。该方法通过对脉冲的到达时间差进行累积方正弦波插值,利用快速傅里叶变换从频域完成对抖动信号PRI中心值的估计。仿真结果表明,该算法能够准确、快速地分选PRI抖动信号。A signal sorting method is presented based on the cumulative square sine wave interpolation to solve the problem of the pulse repetition interval （PRI） jittered signal sorting. The time difference of arrival （TDOA） of the pulses is cumulatively interpolated by the square sine waves, and the center value of the PRI jittered signals is estimated through the Fast Fourier Transform （FFT） in the frequency domain. The simulation shows that the algorithm can rapidly and accurately perform the PRI jittered signal sorting.
