首先提出了一种在双星无源飞行器主动段探测中,可同时估计双星测量的系统误差并给出目标预测轨道的方法.将卫星测量值误差在小角度条件下转化为卫星测量轴的偏转角,以双星逐点交汇定位法得出的轨道为基准估计系统误差,利用最小二乘思想将模型参数估计问题转化为优化问题,使用遗传算法对目标飞行器模型参数进行估计.而后讨论了一种通过加强模型约束,由单星无源探测估计目标轨道的方法.
Firstly, a method of simultaneously estimating the systematic errors of binary satellite measurements and providing the target prediction orbits is proposed in the active segment detection of a binary passive satellite, and the satellite measurement error is transformed into the deflection angle of the satellite measurement axis at a small angle , The system error is estimated based on the orbit obtained by the binary point-by-point intersection method and the least squares method is used to convert the model parameter estimation problem into an optimization problem, and the genetic algorithm is used to estimate the target aircraft model parameters. Then, Method to Enhance Model Constraint and Estimate Target Orbit From Single-star Passive Detection.
