The problem of target destruction by anti-aircraft guided missiles is not solved only by using an accurate guidance system but also by using a highly-performant fuzing system. Aircrafts are characterized by high flying speeds and great maneuverability that make its destruction, using a guided missile, by a direct hitting is a very difficult mission. Therefore, the target destruction may be realized by a warhead (W.H) which is to be initiated properly according to the missile-target (ma) encounter conditions. Up to the moment, there has not been a distinct way for evaluation of a fuze performance (F.P) in a specific M/T encounter conditions. The present paper provides a graphical method for the evaluation of F.P . The proposed algorithm of such method is developed and the flowchart is included. The program of F.P calculation is elaborated. The results include the evaluation of radio fuze(R.F) performance in different encounter conditions which take into consideration the variation of missile speed, target speed, maneuverability and W.H characteristics. The proposed method and its algorithm are well-suited for further research towards the improvement of R.F performance.
