A Target Aggregation Method for Sea Radar Detection Based on Task Correlation

Abstract

A target aggregation method for sea radar detection based on task correlation disclosed in the present invention uses target execution tasks as screening conditions to divide targets into multiple groups; in groups with the same task, set the importance level of each target, and calculate The task correlation between targets, and according to the task correlation, position, speed, heading and other information of the target, calculate the aggregation degree of the target, select the target with the highest aggregation degree as the central target, and transfer other targets within the threshold range of the group to The target aggregates. The method provided by the invention can aggregate a plurality of highly correlated targets into one target, reduce the number of targets displayed on the radar screen, and avoid interference to operators due to dense display of targets.

Description

technical field [0001] The present invention relates to the technical field of radar detection target aggregation, in particular to a task correlation-based method for sea radar detection target aggregation. Background technique [0002] The main function of the sea detection radar is to find sea targets and continuously track the targets. The operator observes the movement status of the targets through the radar display and conducts identification and reporting in time. For sea detection radars of different systems, although the number of continuous tracking targets is different, in general, it can reach dozens of batches, especially in fishing boat-intensive areas or coastal areas, the number of targets will increase exponentially, which will also cause radar screen Focusing on the upper target will interfere with the operator, affect the operator's observation of key targets, and even cause misjudgments and missed judgments.

Problems solved by technology

For sea detection radars of different systems, although the number of continuous tracking targets is different, in general, it can reach dozens of batches, especially in fishing boat-intensive areas or coastal areas, the number of targets will increase exponentially, which will also lead to radar screen Focusing on the upper target will interfere with the operator, affect the operator's observation of key targets, and even cause misjudgments and missed judgments.

[0003] Some existing mechanisms can reduce the number of targets to a certain extent, but may also filter out targets that need to be focused on

For example, increasing the target discovery threshold can filter out interfering targets below the discovery threshold, but it is also possible to filter out targets that are below the threshold and need attention; another example is to prohibit discovery in certain areas, etc., to filter out targets in the area. target, but will also filter out targets that may need attention in the area
