Abstract
Disclosed herein are systems and apparatuses for sonar acquisition using a towed platform (e.g., a towfish). A sonar acquisition towed platform apparatus can include one or more sidescan sonars coupled to a towed platform and a gyroscopic sensor array rigidly coupled to an outer surface of the towed platform. The gyroscopic sensor array can be external to the towed platform and to the one or more sidescan sonars. The gyroscopic sensor array can generate sensor information indicative of a heading of the towed platform and a roll of the towed platform. The sonar acquisition towed platform apparatus can further include a transceiver for transmitting survey information including the sensor information obtained using the gyroscopic sensor array and sidescan sonar information obtained using the one or more sidescan sonars, the sensor information corresponding to the sidescan sonar information.
