【摘要】：综合利用GO/AP算法和CST仿真软件分析了顶角切除和角度公差对三角形三面角反射体(Triangular Trihedral Corner Reflector,TTCR)单站雷达散射截面积(Radar Cross Section,RCS)的影响。研究了三种顶角切除的样式,理论分析和仿真结果表明,只要将顶角切除的尺寸控制在垂直边长的10%以内,三种切除样式对TTCR的RCS影响将十分有限。在角度公差方面,研究了两侧面同时向内或向外偏离90°的情况,发现要使RCS缩减量不超过-3 dB,角度公差应控制在0.5°以内。
[Abstract]:Based on GO/AP algorithm and CST simulation software, the angle excising and angle tolerance are analyzed for trihedral triangle reflector (. Triangular Trihedral Corner Reflector. The effects of TTC on the cross section area of radar Cross are studied. The theoretical analysis and simulation results show that there are three types of vertex angle removal. As long as the dimension of the excision of the vertex angle is controlled within 10% of the vertical side length, the effect of the three cutting patterns on the RCS of TTCR will be very limited. It is found that the angle tolerance should be controlled within 0. 5 掳in order to reduce the RCS to less than 3 dB in the case of both sides deviating from 90 掳in both sides at the same time.
