Abstract: A device and a method for detecting main acoustic indexes of multi-beam sonar pertaining to the field of hydrographic surveying and charting technology. The device includes a rotating device and a lifting gear installed in an anechoic tank. The bottom of the rotating device is equipped with a multi-beam sonar that has its rotating plane perpendicular to the direction of track line and transmits signals along the horizontal direction. A standard hydrophone is equipped at the bottom of the lifting gear, and is connected with a signal collector. The device utilizes the standard hydrophone to receive the pulse signals transmitted by the multi-beam sonar and employs the multi-beam sonar to receive the standard sound source signals, designs the detection process for data collection for analysis and research, thereby achieving the detection of the frequency, source level and beam angle of multi-beam sonar.
