Abstract

The invention provides a self-adaptive target tracking information filtering algorithm of a maneuvering strategy. The self-adaptive target tracking information filtering algorithm comprises the following steps: firstly, establishing a target tracking model of multiple maneuvering strategies and multiple motion models, and then, carrying out the target tracking information filtering algorithm under the multiple maneuvering strategies and multiple motion models to obtain a target tracking trajectory. According to the self-adaptive target tracking information filtering algorithm, a maneuvering strategy concept is introduced, the target tracking model of the multiple maneuvering strategies and multiple motion models is established, the maneuvering strategy transition probability matrix is corrected in real time by the error compression rate of unmatched maneuvering strategies and posteriori information, the matching degree of the maneuvering strategies in the target tracking process is improved, and further, the matching degree of a motion model is further improved. Meanwhile, by combining the self-adaptive structure model and Kalman information filtering, measurement information of multiple sensors is effectively fused, and the tracking precision and the stability of target tracking are remarkably improved.

Description

technical field [0001] The invention belongs to the field of target tracking and relates to a target tracking information filtering algorithm. Background technique [0002] With the development of the economy, people's demand for the use of commercial passenger aircraft has increased significantly, and the increase in the number of passenger aircraft has put forward new requirements for efficient air traffic management. At the same time, with the advancement of science and technology, the increase in the flight speed of passenger aircraft and the gradual use of other civil aircraft have posed challenges to how to efficiently manage the air. The premise of efficient air management is to obtain accurate motion state information of each aircraft, which requires the filter tracking algorithm to effectively track various types of targets with high precision. However, the current general tracking algorithm is based on the Kalman filter algorithm, which mainly has the following pr...
