Abstract

The invention provides a method and system for tracking a turning maneuvering target in a three-dimensional space, and aims to solve a problem in the prior art that it is difficult to perform effective tracking on a maneuvering target with a variable turning rate in the three-dimensional space. According to the method or system provided by the invention, turning rate and turning angle estimation is enabled to be combined with sequential Bayesian filter through a prediction module, a turning rate and turning angle estimation module, an update module, a new target generation module and a target state extraction module, state estimation and error estimation of each target at the current moment are determined, and thus effective tracking for the maneuvering target with a variable turning rate in the three-dimensional space is realized.

Description

technical field [0001] The invention belongs to the technical field of multi-sensor information fusion, and in particular relates to a method and system for tracking a turning maneuvering target in three-dimensional space. Background technique [0002] Bayesian filtering technology is mainly used to assist in the fusion and processing of multi-sensor information under the condition of measurement data uncertainty. It is a powerful statistical method tool. However, the current multi-target Bayesian filtering method is difficult to effectively track maneuvering targets with varying turning rates in three-dimensional space. Contents of the invention [0003] The present invention provides a method and system for tracking a turning maneuvering target in three-dimensional space, aiming at solving the problem in the prior art that it is difficult to effectively track a maneuvering target whose turning rate changes in three-dimensional space. [0004] In order to solve the above...
