摘　　要：为评估海面漂浮二十面角反射器的性能,对不同频率雷达波照射下标准二十面角反射器和存在角度误差状态的二十面角反射器雷达散射特性进行了仿真,得到了2种角反射器的散射特点、RCS均值特性及频率对RCS均值的影响。分析表明:角度误差对二十面角反射器的散射特性影响巨大,大幅度降低了角反射器的性能。研究结果为后续工程实践提供了重要支撑。To evaluate the performance of floating Icosahedrons triangular trihedral corner reflectors, this paper simulates the RCS of the standard icosahedrons triangular trihedral corner reflectors and the icosahedrons triangular trihedral corner reflectors with angle error state under the irradiation of radar waves with different frequencies,and obtains the scattering distribution characteristics of these two corner reflectors and the influence on the RCS mean by RCS mean characteristics and frequency.The analysis shows that the angle errors have a huge impact on the scattering characteristics of corner reflectors,and significantly reduce the performance of the corner reflectors.The research results can provide important support for subsequent engineering practices.
