摘要： A sensor arrangement for an active member, especially such as a landmine which is deployed against ground and airborne target objects, including a waking or proximity sensor which is responsive to the approach of a target object. A high degree in the precision of direction-finding, in addition to target classification; can be achieved by means of a larger passive bearing or direction-finding base, such as can be set up through the positioning of at least three microphones about the mine or at a certain distance from the mine. Hereby, such a passive acoustic direction-finding or bearing base evidences the advantage in contrast with essentially the active high-frequency direction-finding, in that the mine cannot be located from the target object and thus is able to remain in constant operation upon the activation of a waking or proximity sensor without any danger of the mine having its presence betrayed. For a remote distance resolution for a multiple target-recognition, there must be evaluated a larger passive measurement base, as a result of which this evaluation, for instance, is then operatively associated with the active sensor (radar).

摘要： A method for activating a mine possessing a specified activation radius; in particular an anti-helicopter mine, which is brought into an alarm condition by acoustic signals. In the alarm condition of the mine, an NLOS-radar is activated, through which the target speed and the target range of a helicopter are detected and the result of the detection is compared with the specified activation radius of the mine. Full activation of the mine is then implemented when the detection result is smaller than the activation radius, or a further or renewed NLOS-radar detection is effected when the detection result is greater than the activation radius of the mine.
