Area defense mine especially an antitank vehicle mine

摘要

The mine (1) includes a sensor system (10) connected to a microprocessor. The sensor system comprises only passive devices with acoustic sensors positioned in an array and a seismic sensor (10), the signals from which are processed to classify the armored target (17) and to determine target motion. The signals are compared with stored data relating to targets to determine the optimum moment for launching the sub ammunition unit having a target seeking detonator from a launching device (3). The microprocessor determines from the signals received by the sensors and from the spacing between the sensors the bearing angle of the target from the mine. The data from the acoustic sensors is compared with characteristic data for different types of targets stored in the memory in order to effect a target classification and determination of target motion from the target speed and from a time function of the bearing angle, and from the time function of the track of the target and from the ballistic properties of the sub ammunition body, an optimum moment for firing the sub ammunition unit is determined.
