测深仪固定误差和比例误差的检测方法

The Constant Error and Scale Error Detection Method of Echosounders

从测深仪的工作原理出发,根据声波在海水介质中的传播特性,设计了一种单波束测深仪固定误差和比例误差检测的方法和检测流程。考虑到声速对比例误差检测的影响,本文还讨论了将声速误差参与平差计算的检测模型公式并对其可行性进行了讨论。

This paper designed a constant error test method and scale error test method of the single beam echosounder, based on the sound wave spread feature in sea water and run principle of echosounder. Taking sound velocity affecting the scale error detection into consideration,discussed the method ,which the sound velocity error calculations adjustment included.
