Sensor arrangement, especially for a landmine
First Claim
1. Sensor arrangement for an active member, especially such as a landmine deployed against ground and airborne target objects;
- said active member comprising a waking sensor responsive to the approach of a target object;
a low-frequency nondirectionally operating NLOS radar including a proximity-dependently operating multi-target extractor;
a direction-finding base including a plurality of microphones for the obtention of a bearing information from the sensor arrangement to target objects;
a memory storage connected to an output of said radar which is periodically updated with information relative to the surroundings obtained from the sensor arrangement, said active member including at least three microphones which are spaced from the active member so as to attain a relatively large base configuration in comparison with the base of the active member, one of said microphones being fixedly located on the active member, and the remaining microphones being connected with the active member, and wherein the microphones which are spaced from each other are arranged for determining their mutual spacing and the distance from the active member.

Abstract
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).
