Abstract EN
We have developed dual sonar equipment and an improved operating method for improving resolution in order to solve the problems of limitations of the optical equipment and the application method of SSS (side scan sonar) in the investigation of damage of underwater structures.
We analyzed the influence factors of the resolution of sonar data through the comparison of resolution and data quality in indoor test.
Also we confirmed the problems about the overlapping area of the dual sonar.
Depth and distance were analyzed as major influencing factors for survey angle.
Specimens were scanned while adjusting distance and towfish angle according to depth change in order to verify applicability of the developed dual sonar in the field experiment.
Optimal resolution was found to be 3 cm in specimen spacing, and 20 sample data items were extracted.
We developed the regression model based on the multiple regression analysis and developed the RealDualSONAR-DAQ tool, the dual sonar optimum operating method program based on proposed correlation equations.
We can use the developed tools to get the value of the major influencing factors for dual sonar operation and obtain high quality sonar data to analyze damage of underwater structures.
