Combined influence magnetic passive-microwave active triggering device for the activation of anti-tank mines and the like

摘要

The triggering device is capable of detecting automatically, by a magnetic sensor (5), the approach of a target of particular characteristics and its entering a zone near to the vertical (B) of the mine (M). Such a device comprises a passive magnetic receiving transducer, non-directional in the azimuthal plane, and a microwave transceiving transducer having a reception/transmission lobe conically shaped, with its axis coinciding with the longitudinal axis (B) of the cylindrical body of the mine (M). Whenever the first transducer detects a moving ferromagnetic target within a preset zone, generates an alerting signal for the second transducer which is activated in order to detect the effective presence of a target within the damaging zone of the mine.
