Abstract
The invention discloses an integrated multibeam echo sounding device, and belongs to the field of underwater survey. In particular, the device comprises the three parts, an underwater acoustic system, an overwater signal processing machine and a control computer. The device has the biggest characteristics that the information gathering specially devised in the underwater acoustic system together with a control unit and a synchronous signal creation unit achieves a real time gathering of sonar data, surface velocity data, attitude data, hydrostatic pressure and temperature data fully synchronously, meanwhile the data are transferred on a real time basis to the overwater signal processing machine and merge organically with the GNSS (Global Navigation Satellite System) and the pressure data, thereby achieving the simultaneous, isospace and isoattitude gathering and processing of all the data. The device can achieve high precision underwater surveying and mapping without the need to cooperate with extra sensors or extra calibration process when in use, can be widely applied to fields of underwater landform and various underwater structures, fine three dimensional mapping of pipelines and the like, and can rapidly achieve the measurement of underwater three dimensional landforms.
