光学接力跟踪的弹道融合

FUSION OF TRAJECTORY TRACKED BY RELAY OPTICAL MEASURE SYSTEM

研究用多台光学设备分段跟踪同一弹道的数据融合问题 ,首先给出弹道参数、测元真实信号的节省参数模型 ,并由此建立弹道跟踪数据的节省参数模型 ,以此融合各接力段数据 .该方法能给出精度较高的完整而分段光滑的弹道 。

In this paper,investigated is the data fusion technique of using multi optical measurement equipment to track the same trajectory.Firstly,we put forward the reduced parameter model of trajectory parameters and real signal of measure unit.On the basis of that,we establish the reduced parameter model of trajectory tracking data.Using this model,data fusion of all relay measure section is successful.This method can give accurate,integral and piecewise smooth trajectory.At the same time,it also provides the estimate of principal system error of track data.
