What is SONAR?
SONAR is a technique that uses sound waves to map or locate objects in the surrounding environment. The premise is quite simple: first, emit a cluster of sound waves in the direction of an object. While a few waves will bounce off it, the remaining waves will be reflected back in the direction of the emitter. The technique isn’t something extravagant that humans have developed in recent years; it has been used by animals such as bats and whales for millions of years.
