Multi-target tracking algorithm based on track management method

Abstract

The invention discloses a multi-target tracking algorithm based on a track management method. The algorithm comprises steps of receiving the measurement data of a multi-source sensor, and converting the positions of all sensor platforms to the same coordinate system; the measurement being preprocessed, and a measurement equation being modeled; performing one-step prediction on the track under each model by using a multi-model tracking algorithm; performing data association on the measurement and the track by using a track management method; using a multi-model tracking algorithm to update the state of the successfully associated track; and using a track management method to complete track generation and track deletion operations, and outputting a track. The method can be applied to the fields of air traffic control, navigation traffic control, modern informatization combat and the like, and is used for tracking a plurality of targets in different heterogeneous sensor monitoring areas, large sensor sampling rate differences, maneuvering target environments and clutter environments; problems of track loss, track disconnection and the like caused by the fact that multi-source sensors cannot be well fused due to coexistence of a high maneuvering target and a low maneuvering target are solved.
