An acoustic simulation approach for testing ADCP

The difficulty of calibrating ADCPs has long been known. This paper describes an acoustic simulation approach to accomplish the functional and accurate calibration of ADCP. By the acoustic approach, the simulation system monitors the ADCP transmitted pulse, simulates the actual backscatter signal that an ADCP would receive, provides wide scope of profiling range and current velocity simulation, thereby allow direct calibration. Application of the simulation system in functional and accurate calibrations and addressing system failures is also introduced.
