Abstract: Taking the advantage of two methods to fuze, this paper proposes a self-adaptive penetrating fuze algorithm which is more flexible and practical. By this method, the burst point control is completed by ‘calculating the depth of the penetrating’ and ‘identifying the complicate medium’. Furthermore the hardware scheme of fuze system is also presented under the Micro-system, utilizing the high-g array accelerometer fabricated by MEMS as the key parts of the fuze and in virtue of the programmable logic device technology. This fuze system can adapt to the complicated battle circumstance and satisfy real-time requirement.
