摘要
在高水期和含沙量较大的情况下,用声学多普勒流速剖面仪ADCP(Acoustic Doppler CurrentProfilers)在进行底跟踪测量时会发生偏差。本文引入全球定位系统的定位技术,将两者有机地结合起来,并进行GPS跟踪方式的方向改正,用于"动底"长江流量测验,降低ADCP的底跟踪模式下的测量偏差。
In the period of high water level and heavy sediments,error occurs during the bottom tracking measurement with Acoustic Doppler velocity profile gauge（ADCP）.This article introduces a new method which combines GPS and ADCP to correct direction errors in the bottom tracking measurement.And the new method is used in the tracking measurement of movable bottom in Yangtze river.
