Abstract (en)
[origin: EP0082729A2] A system is provided for locating and for characterising the source of attempted and/or actual penetration of the security perimeters of relatively large geographical areas. The system comprises an array of structural moment detectors (401, 402, 403) and electronic circuitry (405) for processing and manipulating signals derived from the detectors (401, 402, 403) in such a manner as to produce secondary signals indicative of any seismic forces caused by a penetration of the security perimeter, the effect of extraneous seismic forces being excluded. In one embodiment, the electronic circuitry (405) associated with each structural moment detector (401, 403) is provided in the same housing as the detector to form a unitary device termed a structural information detector
