Simulation of the spinning concentric annular ring reticle seeker and an efficient counter-countermeasure

Abstract

Reticle systems, which are widely used in infrared (IR) missile seekers, are considered to be the classical approach for estimating the position of a target in the field of view (FOV). A new simulation tool is proposed that gives tracking results of the concentric annular ring reticle seeker in various cases. Our simulation model is applicable to the devel- opment of the advanced seekers. When false targets such as flares are present in the FOV, simulation results show that the existing seeker cannot determine the precise target location. To decrease the suscepti- bility to countermeasures such as flares, we propose an efficient counter-countermeasure using signal prediction and correlation. In the simulation results, we ascertain that with our technique the reticle seeker can perform more effective target tracking than previous seekers. © 1997 Society of Photo-Optical Instrumentation Engineers.
