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).
