Tesla Registers New High-Res Radar Unit With FCC

Tesla has registered a new high-resolution radar unit with the U.S. Federal Communications Commission (FCC) and its Office of Engineering and Technology Authorization and Evaluation Divisions, Drive Tesla Canada has reported.

Although the registration will allow Tesla to sell vehicles that have the units installed in the U.S., the documents don’t reveal how Tesla plans to use these new radar units. They could, Drive Tesla Canada noted, form part of the unreleased Hardware 4.0 (HW 4.0) package.

Tesla driver and hacker @greentheonly pointed out that the new radar units have frequency ranges that are similar compared to the Bosch and Continental units Tesla has used before. The units could be used for imaging similar to how LiDAR maps its surroundings with a laser beam.

In a response to another tweet, Green explained that high-resolution radar has the same benefits as radar but at a higher resolution. That makes sense. He added that it potentially has a higher frame rate but noted that this was just speculation for the time being.

Included in the FCC filing is a test report divided into two parts prepared by the Bay Area Compliance Labs Corps. According to Part 1, the test report was prepared at Tesla’s request on its product model, 1541584, and is referred to as the EUT, which is a non-pulsed automotive radar that operates in the 76–77 GHz spectrum while supporting 3 sensing modes.

In 2021, Tesla caused a bit of an uproar by removing radar from its newly made cars. The newly made cars are relying on a pure vision approach. Perhaps Tesla is planning to incorporate radar back into its cars. Some may say this is a good move, and some critics would probably laugh and say “I told you so.” I change my mind all the time on things and this is a wise thing to do once you learn new information. This pertains to all aspects of life — not just Tesla and radar. With this in mind, perhaps Tesla found a use for radar after all?

One thing is for sure, it’s always a learning adventure with Tesla.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
