Abstract

An IR imagin tracker has been developed by the Defence Research Establishment Valcartier to emulate IR seekers representative of the next generation of anti-aircraft missiles. The main application of this tracker is to perform research on the susceptibility of IR imaging seekers to countermeasures such as decoy flares and jamming by modulated sources. The tracker is composed of a 3-to-5 micrometers IR focal plane array camera and fixed optics mounted on a motorized gimbaled platform. High-speed processors are used to process in real time the IR images to detect and discriminate the targets in the tracker's FOV. The digital tracking loop provides tracker stabilization. A multitude of image processing and target discrimination algorithms can be implemented in the tracker. The complexity of these algorithm must take into account the potential processing limitation of the seeker on-board processor. A specific tracking algorithm has been developed to reject false targets such as decoy flares. Its performance has been evaluated in the presence of counterparts by means of a hardware-in-the-loop simulation facility.
