摘　　要：基于CST软件采用SBR算法对新型二十面体三角形角反射器(ITTCR)在10 GHz频点两种极化方式全角域静态RCS进行了仿真。分别采用Lognormal、Weibull、Burr模型对全角域RCS进行统计建模,Kolmogorov-Smirnov检验结果表明Burr具有较好拟合效果。研究成果为ITTCR的性能评估提供重要的仿真依据和理论支撑。The whole domain static RCS of new type Icosahedrons Triangular Trihedral Comer Reflectors was simulated based on CST soflware by using Shooting and bouncing ray（SBR） method in 10GHz of two polarization. Statistical modeling of static RCS by Lognonnal distribution, Weibull distribution and Bun＂ distribution was investigated, the Kohnogorov-Smimov test results show Bun＂ distribution has preterably effect. The results of this paper can provide an important simulation basis and theoretical support for the performance evaluation of the ITTCR.
