specific Embodiment approach 1

[0029] Specific implementation mode one: refer to figure 1 This embodiment is specifically described. A joint detection method for marine targets based on marine radar information fusion described in this embodiment includes the following steps:

[0030] Step 1: Obtain two radar videos;

[0031] Step 2: Obtain the polar coordinate systems corresponding to the two radar videos, and convert the polar coordinate system into a rectangular coordinate system;

[0032] Step 3: Put the two radar videos from their respective Cartesian coordinate systems to the consistent reference point CCRP Cartesian coordinate system;

[0033] Step 4: Use the fusion strategy to fuse the two radar videos under the consistent reference point CCRP Cartesian coordinate system;

[0034] Step 5: Output the fused image.

[0035] Ocean-going ships are generally equipped with two or more marine radar products. Therefore, making full use of the different blind spots of multiple marine radars to carry out ef...

specific Embodiment approach 2

[0040] Specific embodiment 2: This embodiment is a further description of specific embodiment 1. The difference between this embodiment and specific embodiment 1 is that the fusion strategy includes dual radar co-display strategy, combined large display strategy, and combined small display strategy. Strategies and blind filling display strategies.

specific Embodiment approach 3

[0041] Embodiment 3: This embodiment is a further description of Embodiment 2. The difference between this embodiment and Embodiment 2 is that the steps for the fusion of the dual-radar co-display strategy are as follows:

[0042] First render a color for the first radar video, then render a different color for the second radar video than the first radar video and overlay it.

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...
