Under Water Mine Detection Using Sonar
Underwater mines may originate the serious problems for surface and submarine vessels. This paper presents the few methods employed for detection of underwater mining based on sound propagation technique such as Acoustic-Rapid-Off the shelf Insertion, Side Scan Sonar and Synthetic Aperture Sonar. Sonar is used to generate the underwater ground-truth images from the sound waves generated below 200 feet and is a real-time detection and avoidance of mine. From this, the mine can be easily detected and sonar images are the most widely applied technology to detect the underwater obstacles. It provides high performance at low cost. Now-a-days, towed sonars are used because of the problems of ship noise. But the drawbacks are that, the light used to illuminate the target scene through absorption and scattering phenomena in the underwater medium is affected. It limits the use of video cameras as the visibility range reaches only few meters. The underwater images require preprocessing steps and limit the efficiency of edge detection methods as the images have a weak contrast. Apart from all these drawbacks, sonar techniques are commonly used for underwater mine detection and in many other fields.
