Example Embodiment

[0029] DETAILED DESCRIPTION a: reference figure 1 DETAILED DESCRIPTION embodiment of the present embodiment, the embodiment of the present embodiment An offshore marine radar target joint detection method based on information fusion, comprising the steps of:

[0030] Step a: acquiring two radar video;

[0031] Step Two: acquiring two radar video corresponding to the polar coordinate system, and converts the polar coordinates to Cartesian coordinates;

[0032] Step 3: two radar video by the respective rectangular coordinate system to a reference point coincides CCRP rectangular coordinate system;

[0033] Step Four: fusion strategy using two radar video at a consistent reference point CCRP fused Cartesian coordinates;

[0034] Step five: the output image fusion.

[0035] On board ocean-going ships are equipped with two or more of two marine radar product, therefore, take advantage of multiple different marine radar characteristics of each blind, multi-section marine radar fusion va...

Abstract

The invention discloses a marine radar information fusion-based marine target joint detection method, which relates to the technical field of marine radars, and aims to solve the problems that the situation in a blind area cannot be observed and a target in the blind area cannot be effectively tracked due to the fact that a single radar always has shielding in a fixed direction and has a certain detection blind area in the prior art. The method comprises the following steps of 1, acquiring two radar videos, 2, acquiring polar coordinate systems corresponding to the two radar videos respectively, and converting the polar coordinate systems into rectangular coordinate systems, 3, enabling the videos of the two radars to enter a consistent reference point CCRP rectangular coordinate system from respective rectangular coordinate systems I, 4, fusing two radar videos under a consistent reference point CCRP rectangular coordinate system by using a fusion strategy, and 5, outputting the fused image. The problems that blind areas are caused by the installation positions of the two radars or the radars themselves, information utilization is not comprehensive, and targets in the blind areas cannot be effectively tracked can be solved.

Description

technical field [0001] The invention relates to the technical field of marine radar, in particular to a joint detection method for marine targets based on information fusion of marine radar. Background technique [0002] Marine radar, also known as marine radar, is an active detection device for ships to realize the perception of surrounding targets. Due to the limitation of the radar installation environment on ships, a single radar often has a fixed azimuth occlusion, and there is a certain detection blind area, which makes it impossible to observe the situation in the blind area. , and the targets in the blind area cannot be effectively tracked, which has buried safety hazards for the ship's navigation process. Contents of the invention [0003] The purpose of the present invention is to solve the problem that a single radar in the prior art often has a fixed azimuth occlusion, and there is a certain detection blind area, which makes the situation in the blind area impo...
