中文摘要：

镜反射使得雷达接收目标信号起伏变化，从而影响着雷达目标检测性能。本文分析了镜反射下雷达对不同Swerling起伏目标的检测性能，推导给出了不同镜反射系数下雷达对不同Swerling起伏目标的检测概率数学表达式，仿真分析了多种镜反射场景下雷达目标检测性能以及镜反射对雷达目标检测性能的影响。

英文摘要：

Specular reflection interfere with radar received target signal, which influences radar target detection performance. This paper analyzed radar detection performance for Swerling fluctuation targets in specular reflection circumstance. Radar detection probability and false alarm probability for Swerling fluctuation targets with various specular reflection coefficients are derived. Radar detection performance for Swerling fluctuation targets in various specular reflection circumstances are analyzed by simulations.
