FIELD: influence firing mechanisms, whose principle of operation is based on measurement of variation of the geomagnetic field near armored targets at a high-speed approach to them. SUBSTANCE: electronic unit of the magnetic time fuze with induction-type sensor 1, consisting of coils on cores 7,8,9,10, each connected with amplifier 11,12,13,14, respectively, and electronic unit 2 comprising adder 19, integrator 20, reset generator 21 and actuating unit 24, additionally uses two differential amplifiers 15 and 16, two gates 17,18, preliminary command unit 23 and automatic setting correction unit 22, whose output is connected to the first input of actuating unit 24, and the output of integrator 20 is connected to the second input of actuating unit 24 and to the inputs of automatic setting correction unit 22 and preliminary command unit 23, whose output is connected to the input of reset generator 21, whose output is connected to the first input of integrator 20, whose second output is connected to the output of adder 19, whose inputs are connected to the outputs of gates 17,18, respectively, whose inputs are connected to the outputs of differential amplifiers 11,12,13,14, the inputs of the first of them are connected to the amplifiers of one pair of coils oriented by the magnetic axes towards the fuze motion, and the inputs of the second differential amplifier are connected to the amplifiers of the other pair of coils oriented by the magnetic axes perpendicularly to the direction of fuze motion, the distance between the coils of each pair equals R/6. EFFECT: reduced error in the distance of initiation of explosive from the surface of actual targets to a distance not exceeding R/6 from the preset point on the trajectory of approach to the target, where R-typical dimension of target. 1 dwg
