Marine radar detection target aggregation method based on task correlation

Abstract

The invention discloses a sea radar detection target aggregation method based on task correlation. The method comprises the steps: taking a target execution task as a screening condition, and dividing a target into a plurality of groups; in a group with the same task, the importance level of each target is set, the task correlation between the targets is calculated, the aggregation degree of the targets is calculated according to the task correlation, the position, the speed, the course and other information of the targets, the target with the maximum aggregation degree is selected as a center target, and other targets in a threshold range in the group are aggregated to the target. According to the method provided by the invention, a plurality of targets with relatively strong correlation can be aggregated into one target, the number of the targets displayed on a radar screen is reduced, and interference to an operator due to dense display of the targets is avoided.

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.

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
