PULSED CONDUCTIVITY SENSOR

A NEWLY CONCEIVED SENSOR USES PULSED RF ENERGY CONDUCTED ALONG THE GROUND SURFACE TO IMMEDIATELY DETECT ANY OBJECT OR PERSON CROSSING A SELECTED AREA. THE SENSING ELEMENT IS THE GROUND ITSELF SINCE GROUND CONDUCTIVITY (RESISTANCE -1) CHANGES WHEN COMPRESSED BY THE WEIGHT OF AN OBJECT. USING ADVANCED SIGNAL PROCESSING TECHNIQUES, THE SENSOR TRANSLATES THE CHANGE IN GROUND CONDUCTIVITY INTO A WARNING SIGNAL THAT CAN BE CALIBRATED TO RECOGNIZE INDIVIDUALS, SMALL ANIMALS, VEHICLES, ETC. BY SETTING A THRESHOLD LEVEL THE SENSOR CAN BE USED AS AN INTRUSION DETECTOR TO PROTECT TACTICAL EQUIPMENT; A COMPLETE PERIMETER AROUND AN AREA CAN BE COVERED BY THE SENSOR SYSTEM USING SEVERAL SMALL, PORTABLE UNITS. THE SENSOR SYSTEM DOES NOT USE RADIATED FIELDS AND SHOULD BE TOTALLY TRANSPARENT TO DETECTOR BY HOSTILE FORCES. INSTALLATION, CHECKOUT, CALIBRATION AND OPERATION OF THE SENSOR SYSTEM CAN BE ACCOMPLISHED BY A SMALL TEAM (2-3 MEN) IN LESS THAN TWO HOURS FOR A PERIMETER OF A FEW KILOMETERS.
