As the electronic technology gets advanced day by day the methodologies too should update. For the purpose of ranging various methods such RAdio Detection And Ranging (RADAR), LIght Detection And Ranging (LIDAR) and Sonic Navigation And Ranging (SONAR) etc is used. Later, by adapting the earlier technologies and further by modifying the purposes of detection and ranging in navigation, the technology of Sonic Detection And Ranging (SODAR) is used. The SODAR can be defined as a child of SONAR and also a twin of Echo sounder. The echo-sounder is used only for ranging. But the SODAR use low frequency wave of 33 KHz to measure the underwater depth and also to detect the objects below water medium. So this work comprises with the designing of a SODAR system and to evaluate the underwater sea floor environment and also to measure the depth of the sea floor.
