Paper Abstract

Multicolor discrimination is one of the most effective ways of improving the performance of infrared missile warning sensors, particularly for heavy clutter situations. A new tactical airborne multicolor missile warning testbed was developed and fielded as part of a continuing Air Force Research Laboratory (AFRL) initiative focusing on clutter and missile signature measurements for effective missile warning algorithms. The developed sensor test bed is a multi-camera system 1004x1004 FPA coupled with optimized spectral filters integrated with the optics; a reduced form factor microprocessor-based video data recording system operating at 48 Hz; and a real time field programmable gate array processor for algorithm and video data processing capable of 800B Multiply/Accumulates operations per second. A detailed radiometric calibration procedure was developed to overcome severe photon-limited operating conditions due to the sub-nanometer bandwidth of the spectral filters. This configuration allows the collection and real-time processing of temporally correlated, radiometrically calibrated video data in multiple spectral bands. The testbed was utilized to collect false alarm sources spectra and Man-Portable Air Defense System (MANPADS) signatures under a variety of atmospheric and solar illuminating conditions. Signatures of approximately 100 missiles have been recorded.
