摘　　要：针对现代雷达信号的复杂性和模糊性以及信号在时间上的冗余性等特点,将模糊匹配和D-S证据理论相结合。在信号的积累和求取模糊隶属度的基础上,用D-S证据理论对隶属度进行融合,有效地解决了雷达信号识别的不确定性问题,同时充分利用了信号在时间上的冗余信息,提高了雷达信号的识别效果。仿真试验证明了该算法的有效性。Aiming at the complexity and fuzziness of modern radar signals and the redundancy characteristic of the signals on time,fuzzy matching is combined with D-S evidence theory. The method solves the problem of indeterminacy of radar signal recognition by means of accumulating signals and getting the fuzzy subordinate, and utilizes the temporal redundancy of radar signals effectively and improves the effect of radar signal recognition. The simulation shows that the method is effective.
