Paper Abstract

A new tactical airborne multicolor missile warning testbed was developed as part of an Air Force Research Laboratory (AFRL) initiative focusing on the development of sensors operating in the near infrared where commercially available silicon detectors can be used. At these wavelengths, the rejection of solar induced false alarms is a critical issue. Multicolor discrimination provides one of the most promising techniques for improving the performance of missile warning sensors, particularly for heavy clutter situations. This, in turn, requires that multicolor clutter data be collected for both analysis and algorithm development. The developed sensor test bed, as described in previous papers1, is a two-camera system with 1004x1004 FPA coupled with optimized filters integrated with the optics. The collection portion includes a high speed processor coupled with a high capacity disk array capable of collecting up to 48 full frames per second. This configuration allows the collection of temporally correlated, radiometrically calibrated data in two spectral bands that provide a basis for evaluating the performance of spectral discrimination algorithms. The presentation will describe background and clutter data collected from ground and flight locations in both detection and guard bands and the statistical analysis to provide a basis for evaluation of sensor performance. In addition, measurements have been made of discrete targets, both threats and false alarms. The results of these measurements have shown the capability of these sensors to provide a useful discrimination capability to distinguish threats from false alarms.
