It is technically incorrect to talk about bat “radar”, since they do not use radio waves.
It is sonar. But the underlying mathematical theories of radar and sonar are very similar, and much of our scientific understanding of the details of what bats are doing has come from applying radar theory to them.
The American zoologist Donald Griffin, who was largely responsible for the discovery of sonar in bats, coined the term “echolocation” to cover both sonar and radar, whether used by animals or by human instruments.
