The use of multibeam echo sounders (MBES) has grown more frequent in applications like seafloor imaging, fisheries, and habitat mapping. Calibration of these instruments is important for understanding and validating the performance of MBES. For echo sounders in general, different calibration methodologies have been developed in controlled environments such as a fresh water tank and in the actual field...
Calibration can greatly increase the utility of collecting seafloor backscattering strength with multibeam echo sounders (MBES). A calibration procedure to determine high resolution, three dimensional transmit and receive beam patterns of a Reson SeaBat 7125 MBES was performed using the fresh water calibration tank at the University of New Hampshire. The measurements employed an omni-directional Reson...
Multibeam echosounders (MBES) are widely used for hydrographic surveys and are currently installed on numerous operational platforms. Many of these systems are capable of recording intensity information from the returned acoustic signal in addition to the detected depth solution. There is increasing interest in using this intensity data to remotely characterize the seafloor. Depending on the processing...
