MOVING OBJECT DETECTION SYSTEM USING INFRARED SCANNING

摘要

An infrared moving object detection system comprising first and second infrared detectors and an optical scanning system mounted in an aircraft for scanning along first and second paths on the ground, with the detectors receiving infrared radiation from objects in the two paths. One path is a small angle ahead of the aircraft, and the second path is the same as the first path when the aircraft is directly above it. Electronic circuit means compare the infrared information in the two paths to determine whether "hot" objects are in the same place in both paths, and, if they are not, it is known that one or more objects are moving objects.
