Similarity identification of characteristic curves of environment stimulus for fuze safety system

Abstract

For the current problems of limited environmental information, weak environment stimulus, and difficult to distinguish from interference environment stimulus faced by low-rotation munition fuzes in arming, this paper proposes a similarity identification method for characteristic curves of environment stimulus based on Euclidean distance (ED), and corresponding similarity index. By judging the similarity between real-time speed curve and standard curve, abnormal curve and standard curve respectively, the reasonableness and reliability of similarity index and the feasibility of using it as the predetermined condition for fuze arming are confirmed.
