Multiple model tracking algorithms based on neural network and multiple process noise soft switching

A multiple model tracking algorithm based on neural network and multiple-process noise soft-switching for maneuvering targets is presented. In this algorithm, the “current” statistical model and neural network are running in parallel. The neural network algorithm is used to modify the adaptive noise filtering algorithm based on the mean value and variance of the “current” statistical model for maneuvering targets, and then the multiple model tracking algorithm of the multiple processing switch is used to improve the precision of tracking maneuvering targets. The modified algorithm is proved to be effective by simulation.
