Abstract

A multi-element double ring detector which can track a target effectively under infrared (IR) countermeasure conditions is presented. Dual band IR counter-countermeasures can be performed by the detector to distinguish the target from target–flare mixed signals. Middle and short IR wavelengths are used for target and IR countermeasure detection, respectively. With a special design, unique dual band signals will be outputted by the detector when a target spot is located on the center of the detector. By comparison, the typical single element ring detector has a “dead spot” in this case, which is undesirable for target identification. Relatively high tracking accuracy and low cost indicate that the presented method has a potential application.
