Abstract
The invention pertains to a modulation method at pick-up of the amplitude of the secondary lobes of the radiation pattern for a hyperfrequency antenna and the method application for sensing and eliminating the jamming effects of jammers. According to the invention, we place as a filter (4) close to the reflector (1) which reflects the transmission-pick-up beam of the antenna, the filter having at least one network of conductive wires loaded with variable controllable resistors, such as diodes. During transmission, we make the filter (4) transparent by having strong equal currents travel through the wires, while at pick-up we modulate the amplitude of the currents traveling through the wires in order to obtain the desired distortions of the pattern. The invention especially applies to the sensing and elimination of the jamming effects produced by jammers.
