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.
