Abstract (en)
[origin: US4344077A] 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.
