Problems solved by technology

[0004] Due to the measurement error of the sensor, especially in the dense target environment or the occasions where there are many intersections, bifurcations and maneuvering tracks, it is very difficult to judge whether the tracks from two local nodes correspond to the same target by only using the motion information of the target. difficult

Abstract

The invention discloses a track association method based on target motion information and attribute information, comprising the following steps: step 1: multi-sensor collects motion information and attribute information of multiple targets; step 2 calculates track association degree based on target motion information Step 3 calculates the track correlation degree based on the target attribute information; Step 4 weights and fuses the track correlation degree in step 2 and step 3; The invention uses the track association degree based on the target attribute information as the weight to correct the track association degree based on the target motion information, and measures the conflict between the target attribute information, so as to avoid the false association and missing association of the track, and improve the target track. The correlation accuracy makes it possible to carry out correct track correlation even when there are many multi-target, interference, and cross and bifurcated tracks.

Description

technical field [0001] The invention belongs to the field of target recognition, and in particular relates to a track association method based on motion information and attribute information. Background technique [0002] In a distributed multi-sensor environment, each sensor has its own information processing system, and a large amount of target track information is collected in each system. Then, an important issue is how to judge whether two tracks from different systems represent the same target, which is the track-to-track association (or correlation) problem. In the case of multiple targets, interference, clutter, noise and many crossing and branching tracks, the problem of track correlation will become complicated. The correct correlation of target tracks is the basis of battlefield target recognition, situation assessment, and battlefield decision-making. Therefore, it is an indispensable part of combat to improve the accuracy of the target track correlation detecte...
