摘要
分析了在连续波（ＣＷ）雷达中利用多频率目标回波相位差进行测距时所存在的严重模糊问题．用模糊函数的概念来评价及改善雷达系统的测距（和测速）性能．为减弱测距模糊，文中还对多频ＣＷ雷达的差频值如何按一定参差关系设置进行了探讨．最后。
In this paper, we have analyzed the serious ambiguity that exists in range measurement by using the phase difference between targets echoes of multi frequency in the CW radar. The extended concept of the ambiguity function is used to criticize and improve the range and speed measurement performance of the CW radar system. How to select the staggered ratio of frequencies difference of the multi frequency CW radar to reduce the ambiguity of range measurement is also discussed. Finally, we have presented and analyzed a method of de ambiguity of range measurement.
