영문 초록

This study developed an electric jig for underwater structure inspection in order to solve the problem of the application of side scan sonar to underwater inspection, and analyzed correlation of empirical data in order to enhance sonar data resolution. To apply tow-typed sonar to underwater structure inspection, this study developed an electric jig. In fact, it was difficult to inspect a cross-section at the time of inspection with tow-typed equipment. With the development of the electric jig for underwater structure inspection, it was possible to shorten an inspection time over 20%, compared to conventional tow-typed side scan sonar, and to inspect a proper cross-section through accurate angle control. With the measured depth in a field, it is possible to calculate an angle of Towfish and the distance from a underwater structure. Therefore, it is judged that it is possible to prevent low-resolution data caused by poor operation of the equipment to inspect a underwater structure and to obtain high-quality raw data necessary to analyze underwater structure damage. This study will contribute to the next coastal disaster prevention technology without doubt.
