Naval operations: Submarine and anti-submarine usage. in the thirties a Blimp altimeter called a Sonicaltimeter was tested on Navy Blimps by Admiral Rosenthal, noted (Blimp admiral). The device was made in Germany by Echolot- still in business. Echolot is a blend word of Echo Location or Echo-Pilot. not a Batty idea but uses in a sense ultra-sound not radar waves.

∙ 15y agoSonar (originally an acronym for sound navigation and ranging) is a technique that uses sound propagation (usually underwater) to navigate, communicate with or detect other vessels. There are two kinds of sonar: active and passive. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used in air for robot navigation, and SODAR (an upward looking in-air sonar) is used for atmospheric investigations. The term sonar is also used for the equipment used to generate and receive the sound. The frequencies used in sonar systems vary from infrasonic to ultrasonic. The study of underwater sound is known as underwater acoustics or sometimes hydroacoustics. Source: http://en.wikipedia.org/wiki/Sonar

Can SONAR be used on land?
SONAR is an acronym created by the navy that is the name of what they use to locate items under water. But if you wanted to, you could say the bats using echolocation on land is a type on SONAR. They basically both use sound to locate objects so they are really not very different at all.
