雷达截面积（RCS）是目标的一个重要特性参数，在理论上分析计算目标的雷达截面积有着重要的实际意义。基于几何光学能量传播的思想，首先推导了一种长球双基地雷达截面积的计算方法，并以此分析了长球的双基地雷达散射截面积，最后对算法进行了仿真计算，仿真结果表明长球的RCS呈现极强的方向性。

[Abstract]
Radar cross-section is one of the most important parameters of target. It is necessary to analyze the radar cross-section of a target theoretically. A new analysis algorithm for bistatic RCS of prolate spheroid is proposed based on the propagation law of geometric optics firstly in this paper. Then based on this proposed method, the RCS for prolate spheroid is calculated. Simulations indicate that the bistatic RCS of the prolate sphere shows a great directivity in space.
