Multibeam Non-rotating Sonar
A multibeam sonar transmits a pulse at a certain frequency along a number of narrow beams. The sonar processor looks at the return signal for each pulse and decides where along that pulse return time lays the strongest return, giving a single point in space.
For instance, the Imagenex Delta-T 837 is a programmable, multi-frequency, digital sonar that can be operated using default settings or its configuration customized for seafloor or water column monitoring.
