Sonar was never 'invented' as such, it was adapted from nature.

Bats, many deep water fish and small bugs rely on sonar. Bats for example are almost all blind and guage their position relative to their prey based on how long it takes for their high pitched calls to bounce off surrounding objects and get back to them.
