This invention relates to a process and means for rapid microwave imaging using UHF waves transmitted by an antenna toward a body to be scanned. According to the invention, body O to be scanned is placed in front of a transmitting antenna A and various signals forming the various points of the image are analyzed in a collector-unit RC consisting of a diode-conductor panel 1 and a wave-guide stack 2 and are then transmitted to a receiver R.

Process and means for rapid point by point survey of body scanning

Lens for electronic scanning in the polarization plane

Process to attenuate or cancel certain side lobes of a microwave antenna pattern by using a network of parallel wires loaded with resistances that are adjustable at will, arranged as a filter in front of the antenna. Application of this process to the elimination of the effects of active or passive interferences, as well as to the localization of jammers. Adaptive filter for microwave antennas.
