Abstract

This paper is the third and last in a series dealing with spatial and directional noise and its effect on FLIR performance. First a simplified version of the FLIR90 MRTD model is explained. Then it is shown that the characteristics of various 3-D noise elements can be used to develop the correction functions k_h(f) and k,_v(f) which adjust the horizontal and vertical MRTD upward to account for additional system noise not accounted for by the conventional NETD. The current version of FLIR90 uses k_h(f) and k_v(f) evaluated at f₀ and used as constant adjustments kx and ky. FLIR92, to be released early in 1992, will use the full frequency dependent functions kh and k, This method of MRTD prediction using a correction process to account for 3D noise is validated using several examples covering second generation FLIRs and staring systems.
