Latest Patents

One of his latest patents is the "Airborne Metal Detecting Radar." This invention describes a method and arrangement for an airborne radar system that is particularly adapted to detect large metal targets concealed by camouflage or natural foliage. The system includes an antenna that transmits a continuous wave electromagnetic signal with a selectable frequency, which is designed to maximize penetration through camouflage and enhance detection of metal targets. The arrangement utilizes receivers connected to both in-line and crossed receiving antennas to detect reflected radiation from the terrain and targets.

Another significant patent is the "Dipole Array with Phase and Amplitude Control." This invention employs a bistatic VHF Doppler radar to detect and track intruders crossing a large annular surveillance zone surrounding a high-security installation. The system features a central omni-directional transmitter that radiates a continuous wave signal, with predetermined receiver antennas strategically placed around the surveillance zone. The technology allows for the detection of intruders by analyzing Doppler cycles of phase change, generating alarm signals, and providing tracking data.
