摘要
为计算弹道中段进动锥体目标的动态RCS,根据中段弹道目标的运动学特性,利用椭圆弹道理论仿真计算出了中段弹道;同时根据导弹与雷达的空间几何关系,求得弹头实时视角值。然后利用高频区理论计算方法计算出弹道中段进动目标的实时RCS值。仿真结果与理论分析相比较,证明了所提方法的有效性。
In order to compute the dynamic RCS data of coning targets in midcourse, based on the kinetic characteristic of ballistic targets in midcourse, the trajectory was simulated by using the ellipse trajectory theory. Then the dynamic visual angle was worked out through computing the space geometry connection of radar and mis- sile. Finally, the RCS of the targets under the given scene was calculated with the high-frequency method. Com- pared with the theory analysis, simulation results show the effectiveness of the method.
