摘要 建立了低轨红外预警星座的三维成像观测模型,分析了多测量因素条件下低轨红外预警星座的无源定位精度,研究了不同星座布局条件下像平面测量误差、卫星位置测量误差以及欧拉角测量误差等因素对定位精度的影响。仿真实验表明,本文的定位精度分析方法能够有效分析低轨红外预警星座的定位精度。从仿真实验结果得到了一些可用于低轨红外预警星座设计和传感器调度的指导性结论。 An 3D model of the LEO infrared early warning constellation is constructed. Taking account of the error of the image plane, the satellite position and the Euler angle, the accuracy of passive loction using the LEO infrared imaging constellation is studied in detail. Various constellation configuration is also considered in the analysis. The efficiency of the positioning accuracy analysis method is corroborated by the results of the simulation. Furthermore, some instructive conclusions from the results of the simulation are drawn that can be used for reference in designing constellations and collocating passive sensors to improve location accuracy.
