The following attempts to explain: A pulse of sound is radiated vertically under the hull of the ship from the transmit array. With the application of very sophisticated processing at the receive array the returning echo is divided into 200 beams. Thus a swathe of data of up to 4 times the water depth is collected.

WebEchosounders are a type of sonar commonly used for a variety of tasks, including navigation, measuring bottom depth, and detecting schools of fish and plankton. Single beam echosounders emit a pulse of sound in a narrow cone (2°-12°).
