摘    要:根据某空间飞行器及目标几何模型,用高频近似法计算飞行器的电磁散射和角散射线偏差等,计算结果与矩量法(MOM)及暗室测试结果吻合,验证了算法的正确性,并给出了该空间飞行器雷达散射截面积(RCS)的统计结果、角闪烁在近距离的变化,以及模拟运动过程中散射特性随时间的变化。结果表明:该空间飞行器点频后向RCS满足χ2分布模型;在远场,角闪烁引起的线偏差与距离基本无关,在近场,线偏差与距离密切相关;动态散射特性与运动中的相对姿态和距离等密切相关。

关 键 词:空间飞行器  雷达散射截面面积  角闪烁  近场

Abstract:According to the geometric model of some space flight and target,the electromagnetism scattering characteristic of the space flight was calculated by the high-frequency approximated method in this paper.The computation results were agreed with the data measured and calculated by the method of moment(MOM),which validated the method.The statistical radar cross section(RCS) of the space flight,the angle-glint variety with distance and the scattering characteristic variety with time were given out.The research ...
Keywords:Spacecraft  Radar cross section  Angle-glint  Near-field
