PHASED-ARRAY RECEIVER, RADAR SYSTEM AND VEHICLE |
摘要 |
A phased-array receiver comprises a plurality of analog beamforming receive channels, each comprising an antenna element arranged to receive a radio frequency signal and a channel output arranged to provide an analog channel output signal. At least one of the plurality of analog beamforming receive channels comprises an in-phase downconversion mixing circuit connected to the antenna element and a local oscillator source and arranged to provide a downconverted in-phase signal to a phase rotation circuit, and a quadrature downconversion mixing circuit connected to the antenna element and the local oscillator source and arranged to provide a downconverted quadrature signal to the phase rotation circuit. The phase rotation circuit is arranged to provide to the channel output a phase-shifted analog output signal generated from the downconverted in-phase signal and the downconverted quadrature signal.
