摘要
讨论了下放式ADCP信号接收过程中的TVC增益补偿控制策略。结合下放式ADCP的工作特点,从能量节约的角度采取了同时测底测流的工作模式。针对此种工作模式,提出了按区间分段的TVC增益补偿控制策略。通过声呐方程和TVC距离-增益模型分析,进行了MATLAB仿真验证,并针对可能出现的问题,提出了以相关函数等效电压作为判据的解决方法。
The strategy of TVC gain control used in Lowered ADCP is discussed. In order to save energy, a new working mode, which uses a single working ping to obtain both current profile and bottom depth, is brought forward. In this mode, a TVC control policy based on section dividing is used. The result is validated through MATLAB simulations based on sonar equations and TVC distance- gain model, and problems which may be confronted are solved by using equivalent voltage of correlation function as criterion.
