Currently, there are two mainstream mmWave radar system architectures on the market: one is the satellite radar architecture. The mmWave front-end sensor chip MMIC directly transmits the collected raw data to the vehicle's central domain controller processor through a high-speed interface (Serdes/Ethernet), and the raw data processing is performed in the central domain controller. The other is the edge radar architecture. That is, the MMIC and the processor are integrated on one board or the same chip. The MMIC hands over the collected raw data to the processor to be processed into point clouds or target data, and then transmits it to the vehicle's central domain controller processor through a CAN-FD or Ethernet interface for the next step of decision-making. Figure 2-1 and Figure 2-2 are the hardware block diagrams of these two architectures.
