摘要
针对准实时数据处理的特点 ,本文通过对飞行器弹道用次最优节点的样条函数表示 ,建立了多设备跟踪同一弹道的参数融合处理模型 .与实时处理相比 ,由于考虑了弹道的节省参数表示 ,融合模型可同时提供较高精度的飞行器轨道参数和飞行器轨道跟踪系统误差的估计 ;与事后处理相比 ,由于在特征点间采用的是等距节点 ,因此算法的速度快 ,可以满足准实时数据处理的要求 .
Synthesizing the advantages of methods of real time processing and post processing,we construct a reduced parameter fusing model of tracking data,which are observed by multi equipment to track the same ballistic trajectory,via unequal node spline to represent an orbit of aerocraft.With this model,we can provide parameters of the aerocrafts orbit and the estimate of system error of the aerocrafts orbit tracking with higher precision at the same time,that means better quasi real time results of aerocrafts test processing is shown during a short period.
