Installation Deviation Analysis and Calibration of Five-Beam Janus Structure ADCP Ultrasonic Transducer
摘要
Abstract
The acoustic Doppler current profiler(ADCP)is one of the main instruments for measuring water flow rates in the ocean and rivers.Previous studies on the installation errors of ADCP have all focused on the installation errors caused by the displacement of the transducer array after installation on a ship.The installation errors of a 5-transducer Janus structure ADCP caused by the mechanical processing and installation procedures is analyzed.The installation errors are innovatively divided into positioning errors and installation angle errors.It is proved that millimeter-level positioning errors at a detection distance of 100 m are equivalent to 10-3-10-2 degree-level installation angle errors,and the conclusion is drawn that installation angle errors are the most important part of the installation errors.A calibration method based on echo delay ranging combined with a high-precision attitude sensor is designed to correct the installation errors.The influence of different factors on the calibration accuracy during the calibration process is analyzed through simulation,and different calibration environments are selected according to different calibration accuracy requirements.The results show that the calibration method has certain practical value and can be used to calibrate the installation errors of a 5-transducer Janus structure ADCP.关键词
