Abstract
In October 2005, DRDC Atlantic participated with NURC (NATO) and GESMA (France) in a joint trail with the remote, semi-submersible vehicle DORADO. A large number of sidescan sonar images of minelike objects on the seabed were obtained for a variety of ranges and aspects. The positions of these dummy targets are very accurately known. In this particular report, we use this data to investigate the performance of 5 simple detection algorithms. Each of the 5 detections, false alarms, and missed target statistics are presented, as well as an analysis of the missed target statistics as a function of target type and range. The performance of the detectors as their decision threshold is varied (RIC curves) is presented. In addition, the performance gains which can be achieved by combining detectors, or their corresponding filter outputs, are considered.
