ABSTRACT:
A set of seismic detectors is distributed throughout a defense zone in communication with a set of attack or other controllable devices. A seismic signal source controlled by a zone defense coordinator communicates at scheduled times to the seismic detectors and through them to the associated devices to convey mission critical information. The seismic detectors and the attack devices are controlled singularly and/or collectively by self-contained processors. The seismic source may be at a fixed site and is substantially repeatable as well as controllable. The system may be specially adapted to a wide range of terrains including land and water; and from very shallow to very deep water. Targets may be characterized in terms of their typical seismic signatures and the same hardware system used for seismic communication may be also programmed for target detection and device activation.
