弹道导弹再入段动态RCS特性分析

摘要

研究弹道导弹再入段动态RCS特性,有利于防空反导作战中对其进行有效探测和拦截.首先对弹道目标机动航迹进行建模,然后结合坐标转换公式获得目标姿态角变化,最后利用EDITFEKO软件实现对目标动态RCS实时仿真.针对不同再入角的机动航迹,仿真了不同雷达布站情况下目标动态RCS变化.仿真结果表明,弹道导弹侧向RCS大于正向RCS,反导预警雷达应部署在弹道导弹射程之内,使雷达对着弹道导弹侧面.仿真结果为反导预警雷达的部署提供依据.%Dynamic RCS characteristics of ballistic missiles in the reentry are researched,it benefits the validity detection and interception in air and missile defense combats. Firstly,the maneuvering flight path model of ballistic missiles is structured. Then,the change of posture angle is gotten by the conversion of coordinate formula. Lastly,the dynamic simulation is used by the EDITFEKO software. The dynamic RCS for ballistic missiles in different posture angles are simulated in different radars locations. The results show that the side RCS is larger than the forward RCS in ballistic missiles,providing foundation for the location of the surveillance radar for missile defense, which should be located within the range of ballistic missiles to detect them effectively.
