PHASED-ARRAY RECEIVER, RADAR SYSTEM AND VEHICLE |
摘要 |
A phased-array receiver (600) comprises a plurality of analog beamforming receive channels (602), each comprising an antenna element (610) arranged to receive a radio frequency signal and a channel output (628) 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 (614) connected to the antenna element and a local oscillator source (616) and arranged to provide a downconverted in-phase signal to a phase rotation circuit (612), and a quadrature downconversion mixing circuit (620) 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. |
