MULTIBEAM DIGITAL ACTIVE PHASED ANTENNA ARRAY WITH RECEIVING-TRANSMITTING MODULES CALIBRATION DEVICE AND CALIBRATION METHOD Russian patent published in 2019 - IPC H01Q21/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna engineering, particularly to the field of multibeam digital active phased arrays with polarization control during radiation and adaptation to electromagnetic wave polarization at reception and calibration method. Multibeam digital active phased array with polarization control can be used in radioelectronic systems (RES), such as communication systems, radar equipment, and enables to solve multifunctional tasks on the basis of one radioelectronic device.

EFFECT: technical result when using a multibeam digital active phased antenna array with controlled polarization of the emitted EMW and adaptation to polarization EMW at reception with an extended frequency application area, with calibration device of receiving-transmitting modules, consists in realization of compensation of frequency characteristics in digital form after digitization of oscillations, in provision of high antenna directivity, possibility of beams generation at frequencies, frequency distance between which exceeds working bands of DAC and ADC, and device for calibration of receiving and transmitting channels of multibeam digital active phased antenna array makes it possible to increase accuracy and reliability of measurements of their complex transmission coefficients.
