交会对接中雷达测量信息的最优估计

Optimal estimation of radar measurement information in rendezvous docking

基于目标飞行器与追踪飞行器交会对接这一应用背景,对于追踪飞行器上交会雷达对目标飞行器的原始测量信息(斜距、方位角、俯仰角,甚至径向速度),通过建立适当的目标模型以及观测方程,很好地对2个飞行器的非线性相对运动规律、追踪飞行器绕地球高动态旋转特性、追踪飞行器姿态偏差进行了补偿或修正,实现了最优估计,并通过仿真进行了验证。

Based on the application background of rendezvous docking between the target aerocraft and the tracing aerocraft,the nonlinear relative movement law between two aerocrafts, the highly dynamic circumterrestrial rotation characteristic of tracing aerocraft and the attitude bias of tracing aerocraft are well compensated or rectified by the proper modeling of state equation and observation equation. The optimal estimation of the original measurement information （range, azimuth, elevation, maybe radial velocity） of the target aerocraft measured by the rendezvous radar on the tracing aerocraft is realized,which is testified by computer simulation.
