FIELD: antennas for communication systems, radars, navigation, and television engineering. ^ SUBSTANCE: retrodirective antenna array using its antennas in receive and transmit modes has its antennas disposed along straight line and equally spaced apart; it also has valve; in addition n - 1 valve is introduced , each of n antennas being connected to input of power splitter whose output is connected to series-interconnected mixer, differential frequency filter, high-frequency amplifier, controlled phase shifter, and valve whose output is connected to second input of power splitter; second inputs of mixers in each of n channels are connected to respective outputs of radial power splitter whose input is connected to output of reference-voltage generator. ^ EFFECT: enlarged functional capabilities of antenna array, enhanced feeder operability due to separation of receiver and transmitter channels. ^ 1 cl, 1 dwg |
