摘　　要：通过对卫星轨道的建模,分析电磁频谱监视卫星过顶地面雷达时侦收雷达单波束主瓣的截获问题,给出截获雷达波束主瓣时所要满足的条件。并且通过仿真进一步讨论当地面雷达波束主瓣不同仰角、不同波束主瓣宽度时的卫星过顶截获概率。分析表明,基于太阳同步卫星轨道,截获概率随着波束仰角的增大而减小,随着波束宽度的增大而增大。Through building the model of satellite orbit, the interception probability about the single main-lobe of the radar is analyzed when the spectrum surveillance satellite is overhead of the ground- based radar and the necessary condition of the interception about the main-lobe of the radar is obtained. The interception probability is further discussed when the main-lobe of the radar has different beam elevation or different beam width by simulation. The analysis illustrates that the interception probability reduced with bigger elevation of the lobe and increased with broader width of the lobe.
