Aiming at the layer-counting error caused by abnormal signal adhesion due to the interference of stress waves and other factors during the high-speed penetration of the projectile

a layer-counting algorithm for penetration fuze based on multi-sensor information fusion is proposed.The penetration process of the projectile is simulated to obtain the penetration overload signal.The algorithm generates a fusion signal by convolving and weighting the triaxial acceleration sensor and pressure sensor signals with the window function in the time domain.Based on the fusion signal

an identification strategy is designed to achieve accurate layer counting.The simulation results show that the algorithm can extract the characteristic signal of the projectile penetration process

solve the layer-counting error caused by a single signal to a certain extent

and realize the control of the detonation signal.
