Single-beam echosounder (SBES) is widely used to obtain water depths ranging from 0m – 120m (high frequency) and deeper water up to 6000m or more (low frequency) for various applications.
To ensure 100% coverage, multibeam echosounder (MBES) might be the best choice. The system consists of 90°, 120°, and 150° swath, 200 kHz standard and lower frequency for deeper waters. There are two systems available, i-e. Beam-forming and interferometry system.
