An above-the-water system for and method of finding targets, both animate and inanimate, in a marine environment, especially by determining the distance and depth of targets at, above or below the surface of, the water. An optical transmitter transmits infrared and ultraviolet light beams toward different zones of coverage on the water. An optical receiver equipped with a segmented detector separately detects return target reflections. An indicator, including range and depth indicators, provides information as to the distance to the target and, if it is ...
1. A system for searching for targets over an extended range in a marine environment, comprising: a) an abovewater-mounted transceiver for directing a light beam along an optical path forwardly of the transceiver toward water, and for detecting return target reflections reflected off any targets over a field of view; b) means for scanning at least one of the light beam and the field of view over the extended range, including a deviation prism mounted in the optical path for movement relative to the transceiver, the prism having an axis, a non-deviati...
