It is mostly used for security purposes in air forces and spacecraft for protecting them from unwanted collisions by any object. Radio detection and ranging device that is Radar is used to diagnose unwanted objects in a path.

Frequencies 50-330MHz 100KHz-1Mhz Maximum range 100-3500 Km 482 Km Speed More than Sonar. Sonar is mostly used under the water for communication purposes and ranging purposes etc. Usually used Radar is mostly used in space, spacecraft, and aeroplanes, etc. For navigating purposes, Sonar uses sound waves. Wave Type For detection purposes, Radar uses radio waves. Full forms Radio detection and ranging device. Sonar is a navigation and ranging device that uses sound waves or signals to recognise unwanted bodies or objects. Comparison Table Between Radar and Sonar Parameters of Comparison Radar Sonar Definition Radar helps to find or acknowledge us about the unwanted objects or body that may come between our path and may prove to be dangerous for us. It is mostly used in submarines, aircraft, and for communication that is done under the water.

It uses the to, and fro technique for identifying objects, and Its range is somewhat less than Radar. Sonar is navigation and ranging device that uses sound waves or signals for the recognition of unwanted bodies or objects. Radar transmits radio waves or signals which, when colliding with objects that are far away from us, rebound back. It is mostly used in air forces and aeroplanes.
