| Abstract: | For the application of impact point predicting technique in ballistic targets early warning,a method for predicting impact point of ballistic target with unknown ballistic coefficients based on the combination of the Interacting Multiple-Model (IMM) and the Unscented Filter (UF) algorithm is presented. Timeliness and accuracy of the impact point prediction are analyzed from aspects of the convergent speed and accuracy of the ballistic coefficient estimation respectively. Compared with the impact point predi... |
