Renesas' Satellite Radar System for AD/ADAS solution is a radar system with centralized processing. It consists of several satellite units with their respective radar transceivers connected to a central processing unit. This solution was designed with automated parking and surround view monitoring applications in mind.

System Benefits​:

  • 360° radar coverage by combining the detections from the different radar units.
  • Improved performance and reduced cost by limiting data processing on the edge (Range Fast Fourier Transform - FFT) and processing radar data in the central unit.
  • Satellite modules with RAA270205 radar transceiver
    • High resolution with 4TX/4RX 16 MIMO channels, 5GHz modulation bandwidth.
    • Optimized RF performance, low phase noise, low power consumption, and high-speed ADCs.
    • High capacity MIPI-CSI2 interface to the R-Car V4H processing unit.




  • ADAS/AD applications including:
    • Automated parking
    • Autonomous Emergency Braking (AEB)
    • Lane Keep Assistance (LKA)
    • Adaptive Cruise Control (ACC)
