基于RCS幅值特性相似度的浮空式角反射体布放态势寻优

Optimization of position situation of air-floating corner reflectors based on similarity of RCS amplitude characteristic

为应对常规雷达制导反舰导弹的威胁,采用理论分析和建模仿真方法,基于雷达目标的一类重要电磁散射特性——雷达散射截面积(RCS,radar cross section),对双棱锥形浮空式角反射体布放态势进行了寻优,得到了一种与反导舰艇逼近度较高的角反射体阵列。结果表明:考虑角反射体阵列与目标舰艇的RCS幅值特性相似度,较优的布放态势为[6,15],[8,20],[9,15],[11,15],其中在[6,15]情形下,二者相似度达到60.9%。

In response to threat from conventional radar guided anti-ship missile, optimization of bipyramidal air-floating corner reflectors is performed on the basis of important electromagnetic scattering characteristic - radar cross section (RCS), applying the method of theoretical analysis and modeling simulation. A superior air-floating corner reflector position situation is found which has higher simila- rity with the anti-missile warship. The result shows that, given the RCS characteristic similarity between air-floating corner reflector and target warship, the superior position situation is [6,15],[8,20],[9,15] and [11,15]. And according to similarity function defined in this paper, the similarity can reach 60.9 % in the case of [6,15].
