Abstract

An infrared (IR) dual band multi-element detector with the abilities of dual band IR counter–countermeasure (IRCCM) and spatial filtering is presented for effective target detection in a complex tactical environment. The detection elements of the detector are specially arranged like a conventional reticle pattern. With special design, the ratio of radiation intensity from two IR bands can be calculated to distinguish the target from the IR target-flare mixed signal and the two detection bands use a common aperture in the seeker. Without a reticle in the optical system of the IR seeker, the dual band detector can still perform spatial filtering to eliminate background noise effectively. The design details of the detector are presented. The performance of the detector’s dual band IRCCM and spatial filtering are analyzed. Simulation results are presented verifying validity of the presented method.
