Abstract:
1. A system for detecting, locating and identifying incidents of approaching a linear installation, that includes a plurality of sensing units positioned in an array along a linear installation at a distance one from each other, wherein each unit comprises; at least one sensor for sensing seismic or acoustic interference or noise in accordance with configuration of the system, and means for generating a suitable indicating signal; signal processing means for analyzing the signal and comparing the signal to a cache or data bank of seismic or acoustic interference or noise signatures embedded in at least one of the sensing units; and communication means for transferring data from said at least one of the sensing units to a distant command and control center; wherein each sensing unit comprises a plurality of sensors arranged in a linear array pattern for focusing the covering lobe onto an area of desired surveillance in order to provide a calculation of distance using phased array technology.
