Abstract: To improve the real-time performance of penetrating detonation system, a miniaturized (φ 40.0 mm)hard target penetrating detonation system was proposed based on design theory of state network and modularization design of fuze systems. Equipped with real-time digital signal processor (DSP), high-sampling-rate AD7656 and silicon oscillator instead of crystal oscillator, the system could process information in real-time and bear high shock. For the limitations of traditional filtering methods, two adaptive and fast methods were proposed to improve the system and realize real-time over loading information process in penetration. Combining hardware-in-the-loop simulation test and field test, the penetrating detonation system is demonstrated to be reliable under shock loading.
