Application of the Residual Analysis Method for Data Fusion in Exterior Ballistics

摘要

In this study, in order to resolve the problem of data fusion in the trajectory calculation by many measurement elements, the method of calculating the parameters of exterior ballistics is proposed. The fusion is done by the nonlinear regression model of the reduced parameter model. The residual analysis method is used to diagnose and select the measurement elements which take part in solving fusion and the optimum trajectory is selected from the results trajectory. The result of experiments showed that the residual analysis method can diagnose the abnormal measurement elements in the fusion data processing effectively. The fusion result trajectory has good stability, the precision of the trajectory calculation is high and it has good effect of data fusion.
