Sonar Communication

This Paper presents overall views on SONAR Communication Technology. In this paper we will Highlight on some of the Points, like its Applications , Advantages / uses , Types etc. and we’ll see the Working of SONAR. But before that we would like to introduce about SONAR technology in brief. The term sonar is also used for the equipment used to generate and receive the sound for Sound Navigation And Ranging) is a technique that uses sound propagation (usually underwater, as in Submarine navigation) to navigate, communicate with or detect other vessels. Two types of SONAR mainly Active and Passive , are described in our Paper. Both of these are used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. In its Application we’ll see , how it works for Fishes…etc. Next , we’ll see the Future of this Technology. I have tried to Give a Simple and Clear Idea about SONAR Communication technology in this Paper.
