星载遥感器对地面目标的定位
|
摘要
系统和深入地研究了多种星载遥感器对地面目标的定位问题。以目标相对于星下点轨迹的方位角和遥感器的视角作为相对定位的结果参量 ,与卫星轨道参数相结合 ,导出了地面目标经纬度的通用化计算公式。并在此基础上 ,完成了关于地面目标定位误差的完整分析 ,讨论了各误差分量的计算方法 ,导出了一套相应的计算公式。
In this paper, the locations of ground targets by satellite borne remote sensors were deeply explained. The azimuth of target relative to the nadir point locus of the satellite and the sensor's reviewing angle were acted as result parameters in relative location processing. Through these parameters combined with the orbit parameters, the general formulas of the latitude and longitude of the ground target were derived. On this basis, the target's position errors were analyzed completerly, the calculation methods of error components were discussed in detail, and a corresponding calculation formula was also derived.
