Abstract
This paper describes a digital simulation which uses measured infrared backgrounds and targets for the evaluation of various scan and clutter reduction concepts. Measured infrared background images were digitized, edited, and placed in mass storage of a CDC Cyber 172 computer. Software was developed to combine the small 4° x 4°) measured images into a larger scene (, 12' x 12') suitable for most IR homing seeker simulations. Programs were written which perform the scene scanning process, the summation of pixels within a small IFOV, and simulation of the signal processing. Examples are given of the relative signal at the scanner's aperture, the Fourier transform of this signal, and the filtered output obtained via an inverse transform. A comparison of the scan ing noises for a mid-IR versus an LWIR band are shown for a few sky/cloud backgrounds. The peak signal-to-peak background noise in the mid-IR band is also given for a tank located in a few example terrain back-grounds.
