电大目标等离子体隐身的矩量法优化设计

Optimum design of plasma with MOM method for electrically large target stealth

根据高频散射特征,提出典型几何散射中心替代法,用于解决矩量法(MOM)用于电大目标等离子体隐身时的优化设计问题。以某典型电大目标为例,通过仿真分析了该方法的可行性。结果显示,电大目标覆盖利用该方法得到最优参数的等离子体后,不仅目标整体的单站RCS平均缩减与典型几何散射体的单站RCS缩减相当,且任意方向上RCS基本都有10dB左右的缩减,表明用该方法得到用于电大目标隐身的等离子体参数是可行的。

By decomposing the electrically large target into parts and then fulfilling the parameter optimization of plasma against the typical parts in the target,the issue of plasma＇s parameter optimization with MOM method would be solved when plasma is used for electrically large target stealth.Taking a typical electrically large target for example,the simulation results of prove that the method is effective.
