Downward-looking three-dimension and downward-looking multi-beam integrated underwater panoramic three-dimensional imaging sonar

Abstract

The invention discloses downward-looking three-dimension and downward-looking multi-beam integrated underwater panoramic three-dimensional imaging sonar. The sonar comprises downward-looking multi-beam sonar, downward-looking three-dimensional sonar, an underwater control module and a towed body frame, wherein the towed body frame is of an integral flat structure, a downward-looking three-dimensional sonar receiving array is arranged at the bottom of the towed body frame, and a downward-looking multi-beam sonar transmitter and a downward-looking multi-beam sonar receiver are arranged in frontof and at the back of the upper part of the downward-looking three-dimensional sonar receiving array; a downward-looking multi-beam sonar transmitting array and a downward-looking multi-beam sonar receiving array are arranged in the middle of the front of the towed body frame; a downward-looking three-dimensional sonar transmitting array, the underwater control module, a downward-looking three-dimensional sonar transmitter and a downward-looking three-dimensional sonar receiver are arranged at the back of the towed body frame; transmitting and receiving electronic cabins are further arranged in the towed body frame. The downward-looking multi-beam sonar and the down-looking three-dimensional sonar are integrated, buried objects are detected in a panoramic three-dimensional manner, and three-dimensional imaging of the seabed and terrain imaging of the seabed are performed in real time, and equipment exploration capability and detection efficiency are improved.

Description

technical field [0001] The invention relates to the field of marine engineering technical equipment, in particular to a downward-looking three-dimensional and downward-looking multi-beam integrated underwater panoramic three-dimensional imaging sonar. Background technique [0002] With the in-depth development of marine science and technology and marine economy, the cognition and development of the ocean have spread all over the ocean, and the demand for the ability of detection equipment is getting higher and higher. The detection capability of detection equipment is required to extend from offshore to COSCO sea, from Suspended and sunken objects in water extend to geological layers or buried objects below the seabed. Therefore, there is an increasingly urgent need for an ocean panoramic three-dimensional exploration system that can detect suspended, sunken and buried targets. [0003] Among all kinds of small target detection, buried object detection has always been a tec...

Problems solved by technology

[0004] In the prior art, the traditional acoustic detection method is mainly the shallow formation profiler, and its shortcomings are as follows: 1. The shallow formation profiler has low detection efficiency and low resolution, and generally can only be used to detect thicker pipeline targets or relatively Large-scale geological sections are not suitable for detecting small buried targets; 2. Shallow formations are two-dimensional imaging, and only the section images under the equipment can be obtained; The detection efficiency requirements for such detection (such as small target detection and terrain detection) are also rapidly increasing. On the one hand, it is required to improve the detection efficiency of a single sonar, and on the other hand, it is required to use multiple sonars to work at the same time to obtain doubled detection efficiency.
