Animation of a fishing boat using sonar to detect a shoal of fish. Sonar is a technique that uses pulses of sound (blue circles) to detect objects underwater. The sound is reflected from the object or the seabed, and received by a detector. The time between the pulse and its echo is used to determine the distance to the target. | |
