Abstract

The invention is suitable for the field of multi-sensor information fusion and provides a multi-maneuver target tracking method and system suitable for flicker noise. Through a prediction step, an updating step, a fusion step, a generation step and an extraction step, t distributed model is performed on the flicker noise, a variational bayesian method is adopted to approximatively obtain covariances and target states of observation noise under different models and the joint probability density of the freedom degree, multi-maneuver target tracking under the flicker noise is effectively achieved, and the multi-maneuver target tracking precision is improved.

Description

technical field [0001] The invention belongs to the technical field of multi-sensor information fusion, and in particular relates to a multi-moving target tracking method and system suitable for flicker noise. Background technique [0002] The probability hypothesis density filter under flicker noise is an effective method for multi-target tracking under flicker noise. The filter can effectively track non-maneuvering targets under flicker noise, but the filter cannot convert between different models to track the maneuvering target. Contents of the invention [0003] The invention provides a multi-maneuvering target tracking method and system suitable for flicker noise, aiming at solving the problem of effective tracking of multi-maneuvering targets under flicker noise. [0004] In order to solve the above-mentioned technical problems, the present invention is achieved in this way. The present invention provides a method for tracking multiple maneuvering targets suitable f...
