用等相线干涉测量技术绘制等深线图

Drawing Deeptowed Swath Bathymetry Using Isophase Interferometric Technique

声波等相线干涉测量技术主要用于获取精确的等深线数据和高分辨率的声纳图象，中国大洋协会于１９９５年初从美国Ｓｉｍｒａｄ公司引进的ＡＳＭ６０ＳＩ深拖系统就采用了这种新技术。本文介绍了该技术的形成原理．并总结了同传统测量方法相比，该技术的一些主要优点。

Acoustic isophase interferometer technique is mainly used in collecting imagery data of highly accurate bathymetric. AMS 60SI deep-towed system imported by COMRA used the new technology. This paper explains the basic principles and summarizes some of the advantages it holds over traditional surveying methods.
