Reliability Design to Circuit System in Hard Target Smart Fuze

Hard target smart fuze can adaptively control the the burst point of penetrating projectile. How to improve its circuit working reliability to fit the fuze harsh high-g working environment is studied in this paper. A series of practical measures are taken, such as, propose buffer to fuze circuits; use high quality electronic components; and take circuit redundancy technique. Then the conclusions will provide valuable reference for engineering applications of hard target smart fuze.
