Infrared guidance systems. A review of two man-portable defense applications

Abstract

Since the 1950’s infrared (IR) guidance technologies have been increasingly used in various fields including scientific, industrial and military applications. Affording visibility despite light conditions, in military applications IR made possible night vision, as well as seeker systems intended to guide missiles autonomously to their targets. This article presents a historical overview of IR guidance and discusses to of its current applications in portable air defense systems.
