摘　　要：提出了一种基于雷达信号相参特性的分选方法,可有效分选出信号参数相近甚至相同的雷达信号,同时适用于信号重频参差、抖动的情形。算法采用最小二乘估计获取精确的脉冲初始相位和载频,通过相参判别实现相参雷达信号的分选。仿真结果表明,该方法对脉冲初始相位和载频的计算准确度高,最终的测试结果验证了算法的正确性。A sorting method based on the coherent properties of radar signals is proposed,which can effectively sort out the radar signals with similar or even identical signal parameters and is suitable for the case of signal repetition frequency stagger and jitter.The algorithm uses the least-square estimation to obtain the accurate initial pulse phase and carrier frequency,realizing the sorting of the coherent radar signals through coherent discrimination.The simulation results show that this method has high computational accuracy for the initial pulse phase and carrier frequency.The final test results verify the correctness of the proposed algorithm.
