一种雷达目标的动态雷达散射截面模拟

Simulation of Dynamic Radar Cross Section of Radar Targets

为了能够掌握动态目标的飞行特性,提出了一种模拟目标动态雷达散射截面(RCS)的方法。该方法根据雷达目标航迹相关数据,结合测量坐标系和目标坐标系转换原理,采用多层快速多极子算法,仿真建立了目标静态下的RCS数据库。同时,通过编程实现了目标动态RCS模拟程序,并通过分析得到动态目标RCS曲线。该结果表明,雷达目标的动态RCS模拟对掌握目标的飞行特性起到了一定的作用。该方法可以代替RCS实际测量过程,具有实现简单、操作性好等优点。

To grasp the flying characteristic of dynamic target,in accordance with the relative data of the track of radar target,and combining with the transfer principle of the measurement coordinate and the coordinate,by adopting the multi-level fast multi-pole method（MLFMM） simulation,the radar cross section（RCS） database of electrically large target under static condition is established,and the method of simulating dynamic RCS is proposed.The simulation program of target dynamic RCS is implemented,and the RCS curve of dynamic target is obtained.The result shows that the dynamic RCS simulation of radar target is helpful to grasp the flying characteristic of the object,and this method can replace real measurement of RCS,and features the advantages of easy to implement and good operability,etc.
