A Magnetic Sensitivity Penetrator Layer Method for Penetrating Fuzes

Abstract

The invention discloses a magnetic sensitive penetration layer-calculation method for a penetrating fuze. The method comprises the concrete steps of placing a magnetic steel array in the penetrating projectile fuze so as to produce an exciting magnetic field, wherein when a penetrating projectile penetrates through a target plate containing a magnetic conductive medium, the magnetic field intensity in the fuze is changed, i.e. the internal magnetic field intensity is quickly increase firstly and then quickly reduced so as to produce a layer penetration response signal; utilizing a magnetoresistive sensor for detecting the layer penetration response signal, converting the layer penetration response signal into an original pulse type voltage signal, and outputting the original pulse type voltage signal into a microcontroller; utilizing a correlation filter tracking algorithm for filtering the signal, and obtaining pulse type voltage signals with lower noise; and calculating layers according to the number of the pulse type voltage signals. The magnetic sensitive penetration layer-calculation method has the advantages of difficulty in being influenced by speed and vibration, and the like, and can be used for realizing accurate layer-calculation when the penetrating projectile with a large slenderness ratio penetrates through the target plate at a high speed.

Description

technical field [0001] The invention relates to the technical field of fuzes, in particular to a method for penetrating the fuze with a magnetically sensitive penetrating gauge layer. Background technique [0002] In war, in order to maximize the destruction of the enemy's important facilities with layered characteristics buried deep under hard targets such as steel armor, concrete or rocks, it is required that the projectile must penetrate a certain number of layers of the target and explode. In the penetration fuze, the piezoelectric or piezoresistive acceleration sensor is often used to obtain the penetration overload signal, and the layer information is determined by the change of the acceleration of the penetrating bomb during the penetration of the target plate. The acceleration sensor is used to obtain the penetration overload signal. The signal measured by the acceleration sensor contains two components: the rigid body overload of the projectile and the vibration res...
