A VSMM-based Track Fusion Adaptive Switching Algorithm

There is a contradiction between the fusional time and fusional precision when using the former SF and WCF track fusion. A track fusion adaptive switching algorithm based on the VSMM is presented to solve the contradiction between the fusional time and fusional precision during the fusional process. It can switch between different track fusion algorithms according to a switching rule during the fusion process to optimize the calculative time.The simulation proves that this adaptive algorithm decreases the calculative quantity of the track fusion under the situation that it satisfies the demand of the fusional precision.
