用Monte Carlo法和泛函求目标的RCS

RCS CALCULATION OF OBJECTS USING MONTE CARLO METHOD AND FUNCTIONAL

物理光学法是一种有效的分析目标散射特性的方法,但它存在着计算量大和精度低的不足。本文提出了用Monte Carlo法减少计算量和由泛函的概念导出散射场的稳定公式,以改善物理光学法的结果。本文对圆柱和椭球体进行了计算,数值结果表明:采用新方法后,计算量大大减少,数值结果精度有所提高。

Monte Carlo method to reduce computation and the concept of functional to lead to a stationary formula to improve the results are introduced. The numerical results of the coated-material circular cylinders and coated-material spheriods are also given. It is shown that the amount of computation reduces in large amounts, and the results are good.
