METHOD FOR SETTING ZERO OF BEAM PATTERN OF PHASED ANTENNA ARRAY Russian patent published in 1998 - IPC

Abstract RU 2123743 C1

FIELD: antenna equipment. SUBSTANCE: method involves evaluation of source non- normalized phased antenna array with N elements towards jamming f(θ_п), detection of two adaptive M-element antenna array subsets which conform to condition 2M≥f(θ_п), are located on edge of antenna array, and using phase adjustment in their elements. Phase adjustments Δψ_m for m-th pair of antennas (m= 1,2, . . M, index starting from edge) conforms to condition , where ; λ,X₀ is wavelength and array pitch, θ - is angle from normal to aperture, θ₀,θ_п - is main forward direction and jamming direction respectively. Minus in this equation corresponds to elements of left adaptive antenna array subset; plus - to right one. EFFECT: increased speed of setting zero of beam pattern. 3 dwg
