1. A sensory system in certain animals, such as bats and dolphins, in which usually high-pitched sounds are emitted and their echoes interpreted to determine the direction and distance of objects.
2. Electronics A process for determining the location of objects by emitting sound waves and analyzing the waves reflected back to the sender by the object. In both senses also called echo ranging.

1. A sensory system in certain animals, such as bats and dolphins, in which the animals send out high-pitched sounds and use their echoes to determine the position of objects. See Note at bat.
2. The use of reflected sound waves, as by radar or sonar, to determine the location and size of distant or underwater objects.
the fixing of the position of an object by transmitting a signal and measuring the time required for it to bounce back, typically done by radar or sonar and by bats.See also: Sound
