| 摘 要： | 卫星雷达波散射特征是对其进行监测、识别及打击的重要依据，其特征控制同时也是卫星总体设计的重要内容。针对光电传感器侦察卫星的载荷搭载特点和面临的威胁，确定侦察卫星构型约束条件，分析卫星散射结构组成，对不同雷达波散射特性仿真方法进行分析，提出红外侦察卫星结构的RCS仿真方法。以美国DSP卫星为例，对卫星结构剖分，构建电磁仿真模型，采用射线追踪法、物理光学近似法及等效边缘电流法，对DSP卫星进行目标散射特性提取，从入射频率、极化形式等方面分析散射特点，提出光电侦察卫星的散射亮点部位及隐身改进建议，可用于对光电侦察类卫星的监测、识别及打击和指导该类卫星雷达波隐身总体设计。

| Abstract: | Satellites targets scattering characteristics is the basis of the monitoring, identification and striking for the military objectives, the scattering characteristic controlling is also the important part of system design for satellites. Firstly, the boundary conditions of photoelectric reconnaissance satellites configuration was determined, based on the threat of satellites facing and the load characteristics of satellites loading, the composition and character of the complicated satellites' scattering construction were analyzed. The scattering characteristic of typical satellites target was simulated by SBR method, PO method and EEC method on different frequency and angle. The Defense Support Program was taken as an example to build the structure mesh model, electromagnetic simulation model. Based on the scattering simulation conclusion of DSP model for frequency, polarity and incidence angle, the scattering characteristic of photoelectric/IR reconnaissance satellites targets was extracted. The scattering highlights and stealth improvement suggestions were given, which could be used to guide the target detection and stealth design for satellites targets. |
