【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。更多还原

【Abstract】 In view of the problem that Radar Cross Section(RCS), the important feature for the target classification, can only be calculated offline 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 calls the electromagnetic simulation software—FEKO though Matlab software, and calculates real time RCS of all kinds of aircraft, and provides additional attribute observation for target classification. The simulation result shows that the real-time RCS calculated in mono-static, biostatic and general condition can be called correctly, and the effectiveness of the method is verified.更多还原
