METHOD OF FORMING failures in the direction of the source of interference in the radiation pattern of plane phased antenna arrays with rectangular ABROAD revealing

摘要

A method of forming gaps in the directions of noise sources in the diagrams directional planar phased arrays with rectangular boundary aperture, comprising the step of weighting signals received by each transducer by a weighting coefficient, according to which the determination of the weight vector using information about the direction of the signal source and on the distribution of interference sources, as well as functional maximized is selected, the signal power received from zadannog direction to the sum of noise power and interference received by the antenna, wherein the antenna array elements are algorithmically combined in 2M sublattice and in an optimal weight vector selected vector that minimizes functional errors formulated relatively multiplier sublattices therefore the order of the matrices included in the error functional is reduced to M, characterized in that the composition is administered lattice imaginary dummy elements, complementary to the opening of rectangular shape, when combined elements pryamoug ol aperture in 2M sublattices elements that fall on the boundary between the sublattices is introduced into the sublattices weighing 0.5 to splice two sublattices, and 0.25 for four joint sublattice, and in determining the directivity diagrams of the lattice contribution exclude additional elements introduced to the phases of the respective sublattice .
