Problems solved by technology

[0011] The present invention aims at the inadequacy of the track correlation method of the existing sensor data, which is not suitable for the data association of the whole track segment of the trend message and the situation information of the radar target, and provides a trend report with a simple implementation method, a high degree of automation, and good stability. A data association method for the whole track segment of the radar target situation information to solve the problem of multiple track associations where the target track points are sparse and the position measurement error is large, so as to improve the efficiency of intelligence analysis

Abstract

The invention discloses a trend message and radar target state information whole-track data association method comprising the following steps: extracting track information from trend message and radar target state information; using a double-association threshold rule including a fuzzy association threshold and a shape association threshold to make coarse association judgment on whole-track data, forming a target association track pair of the trend message and radar target state information, and determining the mode of subsequent track data association processing according to the result of coarse judgment; for track pair data in line with the fuzzy association threshold, constructing a fuzzy factor according to information corresponding to the target track point location, and then allocating a weight according to the degree of importance of the fuzzy factor, and carrying out fuzzy comprehensive treatment to realize whole-track association; for track pair data in line with the shape association threshold, using a chain code to describe the track shape, and completing whole-track shape association through chain code matching; and finally, carrying out comprehensive association track processing to realize association of trend message and radar target state information whole-track data.

Description

technical field [0001] The invention belongs to the field of target information processing and analysis, in particular to a method for associating a target track between a trend message and radar target situation information. Background technique [0002] With the development of the joint sea and air early warning system, the importance of multi-sensor information fusion has been fully reflected. Among them, the association of radar target track and movement message is of great significance in target recognition. The radar target track mainly refers to the position, direction, speed and other data of the sea and air targets detected by the radar, and the movement message contains some track point information of the sea and air targets. By calculating the characteristics of the target's full track segment obtained by the two methods, the correlation relationship between the two types of target information can be established to provide a basis for further identification of th...
