Problems solved by technology

These unfavorable factors have brought great difficulties to target anchoring and anchor tracking
If the anchor breaks down or fails to lift the anchor, the target will be lost or the target tracking error will be caused, which may cause major accidents, such as collisions, etc.

Embodiment Construction

[0016] Such as figure 1 As shown, it is a schematic diagram of the inventive concept of the realization method of target anchoring and lifting in the ship traffic navigation system of the present invention, which combines the construction environment information map and the technology of correlation matching, and applies it to the ship traffic navigation system The specific implementation steps are as follows, and can cooperate with figure 2 Shown:

[0017] (1) Store the location of the anchor area of ​​different information sources in the configuration file in a certain format; the location of the anchor area is identified by a series of effective line segments on the azimuth, and the end point and starting point of the line segment represent the distance of the anchor area in the azimuth respectively span.

[0018] (2) Construct a point-track clutter map for the anchorage area to generate three types of target tracks, reliable tracks, fixed tracks, and temporary tracks; w...

Abstract

The invention discloses a method for realizing the tracking of vessels in an anchoring / disanchoring state in a vessel traffic navigation system. When targets are anchored / disanchored, the method comprises the following implementation steps of: storing anchoring region positions of different information sources in configuration files in a certain format; constructing a point trace clutter map for anchoring regions, and generating three tracks, namely a reliable track, a fixed track and a temporary track; for anchoring targets, carrying out tracking treatment by using point traces remaining after finishing correlating the fixed track in the anchoring regions so as to eliminate the influence on the anchoring targets caused by fixed targets as much as possible; and for disanchoring targets, carrying out tracking treatment by using point traces remaining after finishing correlating the reliable track and the temporary track in the anchoring regions so as to eliminate the influence on the anchoring targets caused by the fixed targets and normal traveling targets as much as possible. The method has the advantages that the probability of correlation error caused when the targets are anchored / disanchored can be reduced, and the possibility of tracking failure during anchoring and disanchoring is reduced.

Description

A technical field [0001] The invention relates to a ship tracking method in a ship traffic navigation system in the state of anchoring and anchoring, which belongs to the field of radar target processing, and in particular refers to a method for target crossing bridges and Tracking technology in the state of breaking down and lifting anchor. Two background technology [0002] In VTS, when the target breaks down and lifts the anchor, there may be a large number of stationary targets around the target. Due to the reasons of occlusion and too close distance, the target points will be lost, which will lead to the failure of target tracking. At this time, the detection probability of the target will decrease during the process of breaking down and lifting the target, and the radar needs to continue to track it during this process. In this way, from the overall consideration of the monitoring, it is necessary to carry out special treatment on the anchoring and anchoring process o...
