RECEIVING MULTIPLICATIVE PAA Russian patent published in 2019 - IPC H01Q21/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna engineering and can be used in communication and radar systems. Receiving multiplicative phased antenna array (PAA) consisting of antenna arrays, from the outputs of which signals are transmitted to the inputs of the multiplication system, is characterized by the fact that the PAA elements by random sampling are divided into equal parts by the number of arrays, wherein each array is sparse with random distribution of elements along the PAA aperture. All the arrays form a two-dimensional PAA of a given shape (rectangular, round, elliptical, etc.). Elements of the arrays fill the area of the aperture of the phased antenna array completely (without passing the grid nodes). As a result, the maximum level of side lobes of the multiplicative directivity pattern will be approximately equal to (-13.26 dB)L, where L is the number of sub-arrays forming a multiplicative PAA.

EFFECT: high gain of the antenna array at low level of side lobes (LSL) of the directional pattern (DP).
