| 摘 要： | 由BarrickHF雷达海洋回波散射截面方程出发，求出单位波束宽、单位海域的海浪回波散射截面。并用一天线口径为25km，分辨率为1．5km的雷达系统，研究了海来波对HF雷达检测海面上雷达截面积为30dBm2的小船目标和50dBm2的大船目标的影响。

| Abstract: | In this paper, the Barrick's equation for the HF radar cross section of the sea (seaclutter)is used to determine the limitation that this clutter could impose on the detection of ships byHF radar. Target ship radar cross section of 30dBm2 and 50dBm2 were utilized f and a radar antennaaperture of 2. 5km and a range resolution of 1. 5km were assumed for this study |
