基于消声水池的单波束测深仪精度评定方法

洋海回声测深是目前获得较高精度海底地形的重要手段，但其前提是对测深仪进行准确校正。提出在消声水池内用内符合和外符合的方法来评定单波束测深仪的精度和性能指标。实验表明，该精度评定方法和精度评定软件切实可行，能比较客观地检验测深仪的精度。

Precision Evaluation Method of Single Beam Echosounder Based on Anechoic Pool

With the rapid development and utilization of marine resources, we need higher accuracy of submarine topography. At present,the echosounding is the most important method to obtain the high accuracy of submarine topography. This paper designed a method for exact calibrating of echosounder. It proposed that the internal coincidence and external coincidence could be used to evaluate the accuracy and performance indices of the single beam echosounder in anechoic pool. Experiments show that it is feasible to use this method to test and evaluate the accuracy and performance indices of the echosounder. It gave some technical references for accuracy evaluation of oceanographic survey instruments.
