Target modal estimation based near-space hypersonic velocity target tracking method

The invention provides a target modal estimation based near-space hypersonic velocity target tracking method, which comprises the steps of: tracking a target by utilizing an interactive multi-model tracking algorithm, estimating a target movement mode dynamically and in real time, judging the target movement mode by counting target characteristics, and finally turning to corresponding single-mode matched tracking based on the estimated target movement mode. Competition among multiple models is avoided, and the problems of low tracking precision and the like caused by complex calculation and great model competition of an existing near-space hypersonic velocity tracking algorithm are solved. The target modal estimation based near-space hypersonic velocity target tracking method is low in calculation amount and high in tracking precision, and effectively improves the integral performance of the tracking system.
