Abstract
Dual field-of-view detection allows reflected energy from a target to be eived in one detector and extraneous reflected energy adjacent to the target area to be simultaneously detected in a separate detector. Comparison of the desired signal with a threshold level and with the detected extraneous energy level allows superior false alarm rejection while improving sensitivity by allowing reduced threshold levels for the true target. This dual detection in a single receiver allows the receiver to have two separate but immediately adjacent fields-of-view which interact with a transmitted beam to form a pair of adjacent sensing zones. A vehicle such as a missile equipped with this detection system can pass in close proximity to a target and distinguish a true target passing through the established sensing zone from extraneous background signals.
