Abstract: The factors affecting the design of the beam angle of the single beam echo sounder are analyzed and summarized. The constraints and guiding principles of the design of the beam angle are obtained through the simulation and analysis of the affecting factors, such as the transducer size, sonar equation and detection resolution of the echo sounder working at the typical frequency under the different beam angles. It is instructive to the design of the single beam echo sounder.

Key words: single beam echo sounder, beam angle, sonar equation, resolution
