MULTIFREQUENCY ANTENNA ARRAY FOR GENERATION OF RADIO PULSE SEQUENCE IN SPACE Russian patent published in 2012 - IPC H01Q21/00 

FIELD: radio engineering.

SUBSTANCE: multifrequency antenna array comprises a system of generation of a coherent grid of equidistantly misaligned frequencies, N radiation elements (N>2), N controlled phase changers, a system of phase changer control, N balance mixers, N strip filters, a voltage-controlled generator, a generator of signals of arbitrary shape. Control inlets of phase changers are connected to the outlet of the phase changer control system, the outlets of the system of generation of the coherent frequency grid are connected to inlets of controlled phase changers so that signals with various frequencies are distributed along elements of the grid in accordance with a random law. Each outlet of a microwave signal of a controlled phase changer is connected to an inlet of a microwave signal of an appropriate balance mixer, besides, the outlet of the arbitrary shaped signal generator is connected to the inlet of the voltage-controlled generator, the outlet of which is connected with the appropriate inlet of the modulating signal of balance mixers.

EFFECT: development of a multifrequency antenna array with a frequency barrier in a specified frequency band when a sequence of radio pulses is radiated with specified duration and frequency of repetition.
