Kulcsszavak:ultrasonic depth measurement, single-beam sonar, multibeam sonar, comparative study
The study first briefly deals with the surveying principle of sonar devices used in practice for underwater depth measurements. After that, it describes both single-beam and multi-beam ultrasonic measurements and the disadvantages and advantages associated with their use. Then, in connection with the bed survey of a mining pond, the authors undertake a comparative study of the two survey methods, giving and illustrating their results and evaluating the experiences obtained from the research task.
