一种基于环境噪声的被动测深方法
A Passive Fathometer Method Using Ambient Noise
摘要
Abstract
This article researches a passive fathometer method.Based on the array signal processing and the recovery of time-domain Green's function,it can effectively obtain the time-delay information of the signal receiving by array.Further more,it can use ambient noise to achieve depth.This article establishes mathematical model of passive fathometer,analyzes the mathematical relation during the time delay of passive directed and reflected signals that hydrophones received,the size of hydrophone array and submarine depth.The theoretical formula of seeking depth is derived.Computer simulation and experiments verify the effectiveness of the method.The paper provides a new technical approach for passive fathometer of sounding.关键词
