侧扫声纳系统成图中的位移、变形和噪声问题

侧扫声纳声图判读的正确性和准确性对海洋工程的实施和维护中具有非常重要的作用。但诸多影响因素的存在使得声纳声图不能真实反映海底状况。了解这些因素，并在判读过程中尽可能消除其影响，以达到正确和准确判读是非常有意义的。本文将这些影响因素按照作用结果分为位移、变形和噪声3个大类，并对其校正或消除方法进行讨论。

Problems with Displacement, Transfiguration and Noise in Side Scan Sonar System Graphing

The correctness and accuracy of side scan sonar sonograph interpretation play an important role in the implementation and maintenance of marine engineering, but there are many affecting factors to prevent the sonar sonograph from truly reflecting submarine conditions, so it is meaningful to understand these factors and reduce their influences in the interpretation process so as to achieve a correct and accurate interpretation. In this paper, these affecting factors are divided into 3 types, namely, displacement, noise and transfiguration, and the methods for correcting or reducing these factors are discussed.
