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。
Starting from the Barrick HF radar ocean echo scattering cross section equation, the wave echo cross section of the unit wave width and the unit sea area is obtained. A radar system with an antenna diameter of 25km and a resolution of 1.5km was used to study the effect of sea waves on the detection of a small target of 50dBm2 and a small target of 50dBm2 by a radar radar.
