This image shows a screen shot of a sector view from a test of one of our diver detection sensors used in the SPS. Automatic detection tracks for 2 scuba divers are shown as red lines on top of the sector view. In this scenario, the two divers start together from nearly 500 meters range in very shallow water (only 3.5 meters deep). At approximately 350 meters range, the divers follow sea floor as it slopes down to 8-10 meters depth. At 300 meters range, the two divers separate. Then their paths cross at about 150 meters range. They both approach closer before surfacing. In this test, the sensor was deployed on a commercial pier with a small portion of the port side of the sector view shaded by the pier itself. In this picture, the sector view screen shot is shown as a manual overlay on a digital chart.
