ADP(AcousticDopplerProfiler声学多普勒海流剖面仪)是利用声学原理测量河流流量的一种先进仪器,在实际测量中由于受测量环境、人为操作、系统设置、仪器特性等诸多因素影响,使测量的垂线平均流速、流向、水深、流量等数据值有一定误差。该文介绍作者几年来实际测量中的经验及数据后处理的一些技巧,如减少测量盲区影响,以减少测量误差,提高测量精度等。
ADP (Acoustic DopplerProfiler Acoustic Doppler Profiler) is the use of acoustic principles of the river flow measurement of an advanced instrument in the actual measurement due to the measurement environment, man-made operation, system settings, equipment and many other factors, the measured vertical Line average velocity, flow, water depth, flow and other data values have a certain error. This article describes some of the authors’ experience in actual measurement and data post-processing techniques over the past few years, such as reducing the influence of measurement blind spots, reducing measurement errors, and improving measurement accuracy.
