Nonelectronic Countermeasures for Infrared Guided Missiles Part II - Use of Floor as a Countermeasure
Abstract
In a previous report (1) the general problem of providing countermeasures for freefalling missiles equipped with passive infrared homing devices such as the DOVE was considered, and it was concluded that decoy techniques offer the only generally effective means for achieving adequate protection. The present report presents a detailed analysis of the use of FLOOR, which is the most widely known form of the "cold" decoy, but does not concern "hot" decoys, which are treated in a separate report (2). FLOOR has been defined, rather loosely, as a reflecting film on water. As such, it takes advantage of the low radiant temperature of the sky, relative to that of the sea, and therefore functions as a "cold" source rather than as a heat decoy. Since passive detectors such as the DOVE respond to either "warm" or "cold" targets, the use of FLOOR is, in principle, equally as effective as a heat decoy and in addition does not require that energy be supplied to or by the decoy.
