空间动态目标间相对距离解算方法的改进

探讨了在地面光学测量条件下,直接解算空间动态目标间相对距离的方法,以避开首先解算两动态目标位置分量的要求,而有效地简化解算过程.在此基础上,对多台光学测量设备交会的观测数据,应用非线性递推估计,提供精确解算动态目标间相对距离量的方法,它不需按常规方法对观测方程进行线性化处理,有利于解算结果精度的提高,也减少了计算量.

A Better Method to Calculate the Relative Distance between Space Targets

The paper investigates a method to directly calculate the relative distance between space targets by using the data of ground optical measuring equipment. It does not require calculation of the positions of two dynamic targets, so the calculation is simplified. When the measurements come from multiple sets of optical equipment, the paper proposes a nonlinear recursive estimate method to accurately calculate the relative distance between space targets. Linearization of the observation equation is no longer necessary. The method yields a more accurate result and reduces the complexity of computation.
