摘　　要：分析了当前基于窗口函数截获概率模型存在的问题,提出基于能量的截获概率分析模型,将卫星星座和地面辐射源的轨迹、姿态、天线方向图、天线扫描策略、接收机灵敏度、发射机功率等参数纳入模型。利用此模型,分析三星对单目标、重点区域目标的截获能力。并探究目标波束仰角、波束宽度对单目标截获概率的影响,以及卫星不同天线方向图、扫描策略对区域目标截获概率的影响。仿真结果可以为电磁频谱监视卫星的轨道设计,波束扫描设置提供依据。The problems of the current window function based interception probability model are analyzed.An energy based interception probability analysis model is proposed.The trajectory,attitude,antenna pattern,antenna scanning strategy,receiver sensitivity,transmitter power,and other parameters of satellite constellations and ground radiation sources are incorporated into the model.Using this model,the interception ability of three star constellation against single targets and key regional targets is analyzed.The impact of target beam elevation and beam width on the probability of single target interception is explored.The impact of different satellite antenna patterns and scanning strategies on the probability of regional target interception is explored.The simulation results can provide a basis for the orbit design and beam scanning settings of electromagnetic spectrum monitoring satellites.
