Abstract
1. A system for locating a radiating source comprising a plurality of mutly spaced radiation detectors, first means for correlating the output of one of said detectors with the output of a second of said detectors, second means for correlating the output of the second of said detectors with the output of a third detector, means coupled to said first and second correlating means for separately integrating the outputs thereof to produce a pair of integrated signals, and means for delaying one of said integrated signals with respect to the other of said integrated signals, whereby the delay is indicative of the range of the source from the detectors when the maximum amplitude of the delayed integrated signal coincides with the maximum amplitude of the other integrated signal.
