摘要
本文在D Klement等人(1988)工作的基础上提出了一种计算任意复杂形体目标雷达截面(RCS)的新方法——板块法,该方法运算速度快、使用灵活。利用该方法,本文计算了锥、柱等典型散射体的RCS。计算结果与测试结果吻合较好。在此基础上,本文计算了一飞机模型在不同姿态角下的RCS。经与实测比较,结果令人满意。
A new method, panel method, for Radar Cross-Section (RCS) computations of arbitrarily complicated objects is put forward based on the work by D. Klement et al. (1988). The method has a high speed for calculation, and is convenient for application. By the method, the RCS of classic scatterers, for example, cones and cylinders, are computed, and the calculated results agree with the experimental ones. Then, the RCS of a aircraft model at various attitudes are computed, the obtained results agree with the experimental ones also.
