摘　　要：针对运动目标识别中雷达散射截面(RCS)作为重要分类特征只能离线计算、实时性差等问题,提出了一种基于FEKO的雷达散射截面实时计算。该方法利用入射电磁波和散射电磁波的方位角和高低角,通过Matlab调用FEKO电磁仿真软件,实时计算出不同类型飞机的RCS,为目标识别提供附加的属性观测量。仿真结果表明,在单站、双站及任意情况下实时计算出的RCS都能够被正确的调用,验证了该方法的有效性。In view of the problem that Radar Cross Section （RCS）, the important feature for the target classiifcation, can only be calculated oflfine and has poor unreal-time characteristic, a real-time RCS calculation method based on FEKO is proposed. The method uses the azimuth and elevation angles of the incident and scattered electromagnetic waves, and cals the electromagnetic simulation software-FEKO though Matlab software, and calculates real time RCS of al kinds of aircraft, and provides additional attribute observation for target classiifcation. The simulation result shows that the real-time RCS calculated in mono-static, biostatic and general condition can be caled correctly, and the effectiveness of the method is veriifed.
