Modulation Techniques for Defeating Passive Reticle-Based Infrared Systems.

Abstract

A mathematical analysis of an amplitude-modulated (AM), rotating-reticle, infrared (IR) system was conducted. The purpose of this analysis was to construct a theoretical model of the above IR system, so that methods of defeating or jamming such a system could be developed and studied. Using this model, two types of jamming- sinusoidal and noise- were shown to be effective against the AM-reticle system. Three IR modulation techniques-periodic, pseudorandom, and random binary-which produce these types of jamming were presented and analyzed. (Author)
