The Research On Detection And Orientation Of Underwater Cast Object By Sonar Technology

In irrigation projects and interception of the dam, it is necessary to dump a lot of objects into the river in order to stop the flow. With distance being shortened, the water flow speed will gradually quicken, some cast objects of intercepting dam were rushed away because of the water flow. Not only construction materials are wasted but also would the cast objects bring danger under the river bed. This problem is critical and urgent. Therefore, in order to increase the accuracy that cast object is put in the right place of dam, decrease wastage of cast object and increase the security of the river channel, it is deadly necessary to track and monitor dynamically and analyze the distribution and operation trajectory of cast object. In addition, in river repairing works, root rock loss is a serious problem and affects river safety. When the flow speed fastens, the former stable root stones are easily rushed downward and uncertain displacement happened,...
