摘要
某型巡航导弹靶标主要用于对拦截该弹的反导防御系统进行性能评估,而其在雷达照射下的RCS值是进行评估的一项重要指标,为研究其RCS值对反导防御系统中的雷达探测能力的影响,采用基于高频局部性原理的物理光学法(PO)和等效电磁流法(EEMC)的综合来计算测量导弹的RCS值,并在改变雷达照射波入射方位角的情况下对该型导弹RCS的相应改变情况进行仿真分析,得出了该型号导弹的RCS图,为评估反导防御系统地基雷达的性能提供了参考依据。
The drone of a certain model of cruise missile is mainly designed for the evaluation of the performance of the Missile Defense System （MDS） to head off it, and its RCS value in the irradiation of radar is one of important performances in the course of evaluating. In order to research the effect of the RCS on MDS＇s radar detecting power, the paper adopts physical optics measurement and equivalent electromagnetic current measurement basing on high frequency local theory to calculate and measure RCS value of the missile, and simulates and analyzes the certain missile RCS＇s change corresponding to the change of incident azimuth of radar electromagnetic wave. In the end, the paper educes the certain missile RCS＇s figure ,which offers necessary reference foundation to evaluate the performance of MDS＇s ground base radar.
