摘　　要：针对侦察卫星过境预报的军事需求,提出一种侦察卫星对地覆盖区域建模分析方法。在SGP4/SDP4轨道预报模型的基础上,考虑传感器的视场参数和姿态参数,给出观测矢量与地球相交、相切、不相交3种情况下侦察卫星对地覆盖区域的计算方法。以STK软件为对比依据,进行单星和侦察卫星星座对地覆盖区域仿真。试验结果表明:该方法有效可行,可为规避敌方卫星对我侦察提供信息保障。According to the military requirement of reconnaissance satellite transit forecast,a modeling and analysis method of reconnaissance satellite coverage area was proposed.On the basis of SGP4/SDP4 orbit prediction model,the field of view and attitude parameters of sensors are considered.The method of calculating the coverage area of reconnaissance satellite is given when the observation vector intersects,tangents and does not intersect with the earth.Based on the STK software,the coverage area of single satellite and reconnaissance satellite constellation is simulated.The test results show that the method is effective and feasible,and it can provide information support for avoiding enemy satellite reconnaissance.
