Abstract

An airborne identification system is designed, which has been named airborne synthesized friend or foe and electronic countermeasure system (ASIFFC) and incorporates technology of identification friend or foe (IFF) and electronic countermeasure. ASIFFC uses the coordination type IFF technology and the non- coordination type IFF technology, and it has independent capability in identification and tracking. ASIFFC presents a plan that is the combination application of many kinds of identification technology, and it is development trend of IFF technology. In the article, firstly, it carries on the system design to ASIFFC. Secondly, subsystems have been given a minute description. The Sending device of LSID sends radio frequency inquiry signal to the goal object which has been locked by the radar. The receiving device of LSID receives reflection signal of goal object. The LSID is carried on IFF on the basis of the receiving or sending signals. The pattern identification device (PID) withdraws the image information of a goal object and contrasts them with the data in the image database and distinguishes the friend and foe attribute of object. The dual identification technology enormously enhanced the identification reliability.
