METHOD FOR FORMING HIGHLY DIRECTIONAL SCANNING COMPENSATION DIRECTIVE PATTERNS IN FLAT PHASED ANTENNA ARRAY WITH SPATIAL EXCITATION Russian patent published in 2021 - IPC H01Q3/26 H01Q25/00 

FIELD: antennas.

SUBSTANCE: invention relates to antenna equipment and is intended for radio location systems. The technical result is achieved by the fact that nonequidistant subarrays are separated from a flat equidistant antenna array according to the number of compensation channels, highly directional scanning directive patterns (DPs) are formed: a compensation DP of the subarray of each compensation channel and the DP of the subarray of the main channel, wherein the probability of an element being separated into the nonequidistant subarray of the compensation channel depends on the location thereof in the aperture and is determined as the product of the coefficient ensuring isolation of a given number of elements into a subarray of the compensation channel times the difference between one and the ratio of the one-parameter Hansen distribution, the parameter whereof is selected by the criterion of the maximum ratio of the level of the main maximum to the maximum level of the side lobes of the DP of the subarray of the main channel, to the value of the amplitude distribution on the element of the antenna array.

EFFECT: increasing the ratio of the signal energy to the spectral power density of the interference.
