ABSTRACT:
A direction finding system for infrared radiation includes a set of four detectors uniformly positioned about the Z axis of a cartesian coordinate system with individual ones of the detectors having radiation detection surfaces facing the Z axis and being inclined relative to the Z axis. The detectors are inclined relative to an XY plane of the coordinate system. Signals of the detectors are fed into computer storage to permit computation of the direction of a source of radiant energy relative to the Z axis based on a ratio of magnitudes of the signals of the detectors.
