The chip isn't very novel. There are various different configurations of dsp/fpga and arm/powerPC/x86 used for RF.
Typically, the dsp or fpga is used to handle the time critical pieces, i.e. generating RF, and the pc is there to command and collect data.
There are a variety of vendors you can choose from for this type of setup. From SoC to PCIe fpga for a server, all depends on your applicatio.
The application to the automotive sector might be novel.

Put in an FPGA, then you are way over price. The baseband bandwidth for FMCW RADAR is not that much, so they are able to pull this off with a DSP. It’s the RF integration that impressed me. I’m presently using some ADI SiGe mmWave ICs (impressive themselves), and those are close to $300 for the TX/RX pair, and that’s only the RF to analog baseband. The TI part is $55 for a fully integrated chip. Just need a PCB/antenna and supply regulators.

- oldsklgdfth 8y agoI can see that. I'm curious what kind of Rx sensitivity they can get for the HF range.
- janekm 8y agoThe novel part is that the whole radar front end is also integrated, including the RF PAs. Literally just one chip for everything directly connected to the antennas.
