A new tracking algorithm for hypersonic targets

First, motion characteristics of near space hypersonic targets are given and the moving model for aircrafts is built. Then, according to the disadvantage which time sample is a constant when tracking hypersonic targets, an adaptive tracking algorithm of time samples is proposed. This algorithm used the recursion formula method in real time and mixed Singer model with algorithm of IMM. Simulation shows that because of the initial value setting is not reasonable, the new algorithm has bigger local error, but in general, compare with unimproved algorithm, and the new algorithm has better accuracy.
