Abstract

Recent work by BDM for U.S. Army Missile Command (MICOM) indicates that current MRTD-based infrared sensor performance models (e.g., FLIR90/ACQUIRE, MIISPM) may not adequately model the effect of low frequency system noise on predicted system field performance. This paper addresses a computer modeling exercise conducted by BDM using the MRTD-based MIISPM in conjunction with the 3-D noise model developed by D'Agostino, et al., at the US Army NVESD to predict the effect of modifying a low frequency noise specification on the field performance of a hypothetical imaging IR target acquisition sensor that utilizes a second generation infrared focal plane array (IRFPA). Contrary to intuition, computer modeling results indicate that large increases or decreases in the low frequency system noise have little impact on predicted field performance.
