A plurality of radar sensors and radio units are controlled and processed by a signal processing unit (SPU). Each radar sensor receives configuration, control, power management, and calibration messages along with compressed data stream for transmission from the SPU over a multi Giga-bit interface (MGBI). Each radar sensor transmits status messages and compressed received data stream to the SPU over an MGBI. The SPU performs radar signal processing and tracking upon decompressing the data stream received from the radar sensor. Each radio unit receives configuration, control, power management, and calibration messages along with compressed frequency-domain waveform samples for each transmitter antenna port and for each component carrier configured by the SPU over an MGBI. Each radio unit transmits status messages along with compressed calibration data and compressed frequency-domain waveform samples for each receive antenna port and for each component carrier configured by the SPU over an MGBI. The SPU decompresses the frequency-domain waveform samples, and performs radio baseband signal processing including channel estimation, transmit beamforming, and receive beamforming. The SPU establishes and maintains time synchronization with each radar sensor and radio unit connected to it over an MGBI.
