Abstract
This paper presents a dynamic simulation loop that gives tracking results of 2-color concentric annular ring (CAR) reticle seeker. Our simulation tool includes the target/flare model and a proportional navigation guidance loop. The CAR reticle system performance and the flare effects are analyzed in various cases. When a flare is presented in the field of view (FOV), the simulation results show that the reticle seeker cannot keep a precise target tracking. In this paper, we propose a 2-color counter- countermeasure using the least mean square method to cope with a presence of IR flare. The proposed method makes a simultaneous process in two IR wavelength bands: (i) the modulation output in FWIR, (ii) the output in MWIR. The simulation result have shown that our adaptive IRCCM algorithm achieves an effective cancellation of the flare signal with a relatively high intensity.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
