ONAR is the underwater equivalent of radar, and like radar its functions are many and varied. These include the detection, identification, location and speed indication of 'targets of interest'.
There are basically two sonar modes of operation, 'Passive' (receiving or listening) and 'Active' (transmitting and receiving).
Radar operates on the principle of transmitting and/or receiving electromagnetic waves, travelling at approximately the speed of light (3x108 m/sec) through space or the atmosphere.
SONAR on the other hand, relies on sound or acoustic energy in seawater travelling at approximately 1,500m/sec, depending upon conditions such as temperature, depth, and salinity.
