METHOD OF CONSTRUCTING AN ACTIVE PHASED ANTENNA ARRAY Russian patent published in 2019 - IPC G01S13/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna engineering and is intended for construction of active phased antenna arrays (APAA) for radio communication and radar systems. Antenna elements are arranged on front panels of multichannel transceiving modules (MTM) in units of rectangular or triangular grid with pitch along vertical and horizontal, determined by required scanning sector respectively in vertical and horizontal planes, each emitter is connected by a communication line of minimum length to input / output of one of channels MTM, wherein in the transmitting part of each channel the phase shifter is installed, and to isolate the receiving and transmitting parts of the channel, a circulator is used, an antenna web of the active phased antenna array is formed from MTM, installing them next to each other so that the surfaces of their front panels are located in one plane, and the distance between the radiators is kept constant in the vertical and horizontal planes, wherein the front panels of the receiving-transmitting modules function as a screen, forming a heterodyne signal, sampling clock frequency and distributed by distribution system to MTM, in transmitting mode generating transmitting beam with given shape by setting phase and amplitude ratios of transmitted signal in channels of receiving-transmitting modules, in the reception mode, the signal at the intermediate frequency is sampled from the output of each receiving channel of the receiving-transmitting module and the required number of beams of the receiving pattern is generated from the obtained samples.

EFFECT: reduced losses of received and transmitted signals.
