摘　　要：通过软件仿真计算光电转台的雷达散射截面积(radar cross section,RCS)。基于散射的高频局部性原理完成目标的RCS预估,在S、C、X波段,0~3°入射余角条件下对光电转台的RCS进行仿真。将复杂的光电转台分解,研究各部分RCS特性并对光电转台开展隐身设计。对完成隐身设计后的转台进行仿真分析,隐身设计后均值大于0.5 m^(2)的RCS占比约为18.18%,光电转台隐身特性提升明显。The radar cross section(RCS)of a photoelectric turntable through software simulation.Based on the principle of high-frequency locality of scattering,the RCS prediction of the target is completed.Simulate the RCS of the photoelectric turntable in the S,C and X bands,under 0~3 incident residual angle.Decompose the complex optoelectronic turntable,study the RCS characteristics of each part,and carry out stealth design of the optoelectronic turntable.A simulation analysis was performed on the turntable after the stealth design was completed.After the stealth design,the proportion of RCS with an average value greater than 0.5 m^(2)was approximately 18.18%.The stealth characteristics of the photoelectric turntable were significantly improved.
