| Abstract: | Presently, multi-beam sounding system is the most advanced apparatus, whose application will play significant role in flood control & disaster reduction, dike projects monitoring and topographic survey underwater. By comparing measurement of multi-beam sounding system, single-frequency depth sounder and digital depth sounder, the article analyses causes of error and precision for the system. It has proved that multi-beam sounding system with the help of a single-frequency depth sounder can complete topographic survey measurement tasks under special underwater conditions, thus providing scientific evidences for the wide application prospects of multi-beam sounding system. |
