What frequency relationship exists between multibeam and single-beam echo sounders?

Multibeam and single-beam echo sounders operate within the same frequency range because both types of sonar systems are designed for underwater depth measurement and mapping. The frequencies commonly utilized in these systems generally fall between 10 kHz to 100 kHz, allowing for effective detection of the seafloor and underwater features.

By utilizing similar operational frequency ranges, both multibeam and single-beam systems can achieve adequate resolution for various hydrographic surveying tasks. Multibeam systems, however, use multiple beams to cover a wider swath of the seabed, providing more detailed and efficient mapping of the underwater terrain compared to single-beam systems, which typically capture depth data along a single line. The compatibility in frequency range ensures that both systems can be used effectively for similar applications, Merely serving different surveying needs based on the number of beams emitted rather than the operating frequency itself.
