Patent attributes
A method and apparatus employing an array of spaced detectors and a detection circuit to detect disturbance of first and second conductors and provide signals to a computer system to determine both the presence of the intruder and the direction of travel of the intruder. The velocity of the intruder's travel may also be determined. When used with a destruction device to destroy an intruder such as an explosive shell, the lob time and the killing distance may also be calculated and used to fire the shell and to explode it at a position to destroy the intruder. Often the intruder is an armored vehicle or a tank. The conductors may be spaced in an array that has the appearance of a spider web. The conductors may be light weight conductive elastomeric conductors.
