Abstract
A passive radiation bearing (azimuth) sensor including a member having a plurality of radiation detectors mounted in spaced apart relationship therearound and additional structure limiting the receiving field of each detector to a generally conical volume having its apex at the detector. The sensor further includes electronics for determining when the radiation being received has changed from a reference value and which detectors sensed the change, and for calculating from this information whether a transient object is in the field and, if so, its bearing.
