摘要： Apparatus, method, and system example embodiments provide an improved integrated circuit RF front end to simultaneously transmit and receive signals for radar imaging. In an example embodiment, an apparatus comprises a transceiver coupled to a circularly polarized antenna assembly, capable of transmitting circularly polarized signals that are a component of a multi-signal radar beam; a power amplifier configured to amplify a transmit signal, coupled through isolation couplers to the circularly polarized antenna assembly; a phase shifting block circuit configured to perform phase shifting of a local oscillator signal, in response to the receipt of phase control signals, to perform phased-array beam steering of the multi-signal radar beam when the component circular signals are associated with signals transmitted from other transceivers receiving the phase control signals. The apparatus further includes a receiver circuit utilizing a receive phase-shifting circuit coupled to a quadrature down-conversion mixer, for receive beam steering.
