雷达目标分辨是“雷达原理”课程中的重要概念，本文详细分析了相位差对目标分辨的影响，推导得出分辨率与相位差的近似公式。研究表明：雷达分辨率与相位差绝对值具有严格的单调关系，两目标相位相同时分辨率最大，相位相反时分辨最容易，相位未知的情况下，平均分辨率大约为0.8倍模糊函数3dB宽度。上述结论适用于时域、多普勒域和角度域。

Radar resolution is an important conception in the course of Radar Principles. The influence of relative phase on radar resolutions has been investigated theoretically. The resolution formula is derived with respect to the relative phase. It can be seen that the radar resolution monotonously decreases with the relative phase increasing. Especially,the resolution reaches the maximum when the two targets are in phase. Otherwise,the resolution rea-ches the minimum. As for the random relative phase,the mean resolution is 0. 8 time the 3dB width of ambiguity function. This conclusion fits in time,Doppler and angle domains.
