ABSTRACT:
Intelligent hard-target weapons provide a real-time estimation of a medium as the weapon is penetrating through it. Input signals are provided by an accelerometer used as a primary sensor. On-line concurrent processing of the data of a specific length facilitates a few different modes of feature extraction. The processor provides a robust, real-time decision making for the fuze utilizing sensor signals (accelerometer data). The feature sets utilized include (1) amplitude profiles of the signals, (2) their derivative profiles, and (3), the measure of their abrupt changes. The purpose is to provide for detonation at the proper point as the high-speed penetrator passes through various layers such as concrete, steel, dirt, sand, etc. on its way to a valuable buried target. Real-time decision making is provided for the fuze utilizing accelerometer data.
