深海超短基线声学定位系统计算目标水平距离的一种新方法

A New Method to Measure Horizontal Distance of Target by a Deep Ocean Ultra Short Baseline Acoustic Positoning System

对深海环境中工作的潜器或设备载体进行定位测量是深海调查的重要任务之一。本文基于射线声学原理对超短基线声学定位系统的定位数据提出一种迭代处理算法，能够得到非常精确的水平距离测量结果。这种方法对于大洋调查的深拖系统和其他水下设备定位有重要的现实意义。

In ocean survey one task is the positioning of equipment vehicle or towed body which work in the environment of deep sea.In this paper a arithmetic of iteration is represented which is based on the theory of ray acoustics.With this method one may get accurate results of the horizontal distance of target measured by an ultra short baseline acoustic positioning system.The method is beneficial to positioning of deep towed vehicle or ROV.
