The Research Of Underwater Navigation System

In testing the underwater target, for making a way to measure multi-angle way in sea, we need to nicety mastery the distance and the sound incidence azimuth between the measuring ship and the underwater target. We need these parameters to ensure the safe for the shipping.The navigation technique in this disquisition just is for it. It can supply necessary parameters for underwater target safely shipping.The keystone is analyzing the measuring precision and the measuring error.
