Data Process And Software Optimized Design Of ADCP

Acoustic Doppler Current Profiler,ADCP for short,is a kind of new ultrasound equipment for current velocity based on acoustic Doppler and has been widely used.Pulse to pulse coherent measure way is studied particularly and displaying console system is optimized.The principle of pulse to pulse coherent is studied,the basic performance of pulse to pulse coherent is analyzed,the form of sending signal is confirmed,mathematic model of echo is established,pulse to pulse coherent measure way is verified by echo generated from simulation,the element influencing measuring is analysed by simulation and the performance of pulse to pulse coherent in simulation condtion is acquired,data processing procedure is written in DSP and displaying console system procedure is written in computer,complete measure course is realized.A lot of test is implemented in laboratory condtion by ADCP butt-joint calibration system,data generated from various stages from ADCP system is analysed in detail,at last,correctness of pulse to pulse coherent are verified and the ability of pulse to pulse coherent in test condtion is obtained.Also,displaying software is improved,mosaic effect of interface is reduced,the display way of sliding window is implemented and velocity variation resolution is improved,the function of drawing track and flow velocity line is implemented.
