Engineering Physics Annotation << Back Adaptive Adjustment of Azimuth Diagram Moiseev A.A. Adaptive diagram adjustment intended for interference sectors suppression and other sectors preservation. This operation performed by multicomponent antenna. It includes spike subantennas located in pentagon apexes and have partial lambert diagrams in azimuth plane. Preliminary estimation of multicomponent antenna field is linear combination of basis functions correspondent to subantennas. Linear combination coefficients defined from linear system whose second member are signal statuses for interference situations. Directional diagram is normalized square of multicomponent antenna fi eld formed on the base of preliminary estimation using interference statuses. At interference absence azimuth diagram has fi ve lobes with maximums correspondent to components polar angles. At interference presence azimuth diagram represents wide – angle lobe with maximum correspondent to polar angle of interference free component. External angle sectors are locked providing interference suppression. Developed method embrace also intermediate situations with interferences in 2–3 sectors. Keywords: directional diagram, adaptive adjustment, multicomponent antenna, spike subantenna, lambert diagram, basis functions, signal status, wide – angle lobe.
