Systems and methods for labelling sonar data

Abstract

Systems and Methods for Labelling Sonar Data A computer-implemented method is provided of automatically labelling passive sonar hydrophone data for use as a supervised learning dataset, comprising: for a selected passive sonar hydrophone: obtaining actual received sound data throughout a detection time-period, obtaining a hydrophone location, and determining a maximum detection radius around the hydrophone location; retrieving timestamped vessel data associated with vessels within the maximum detection radius during the detection time-period, the timestamped vessel data comprising for each vessel: vessel location information and vessel identification information; determining, for a particular vessel identification information, an estimated received sound metric for each vessel throughout the detection time-period, based on the timestamped vessel data; labelling the actual received sound data, the labels including the particular vessel identification information and being associated with times during the detection time-period where the estimated received sound metric is above a threshold.
