摘要
利用某导弹靶标可对反导防御系统进行性能评估,以满足武器系统的定型、试验和训练的要求;为分析靶标的RCS,文章从基本电磁散射理论入手,介绍了物理光学法和等效电磁流法,并给出了目标表面反射场和边缘绕射场的RCS计算方法;最后利用物理光学法(PO:Physical Optics)和等效电磁流法(MEC:Method of Equivalent Currents)相结合的方法对某导弹靶标模型进行仿真计算;结果表明,该方法运算速度快,计算结果符合导弹靶标RCS的变化规律,可以满足工程设计的需要,为后续的研究提供了可信的数据。
Missile＇s drone is mainly used to evaluate the capability of the Missile Defense System, so that we can find out whether it can meet the requirement of weapons systems＇ stereotypes, testing and training. In order to analyze RCS of missile drone, method of physical optics （PO） and equivalent currents （MEC） are introduced based on electromagnetic scattering theory. Then, calculation of reflect field and edge diffraction filed are presented. Simulation was carried through on certain missile drone by using PO and MEC. The results show that this algorithm can satisfied the analysis need for the RCS calculation of missiles, which provides credible data for the following research.
