Upgrading Autopilot: Seeing the World in Radar
More info: Tesla&#x27;s radar is a Bosch device. Either the Bosch LRR4, which is several years old, or the Bosch mid-range radar. Bosch has made about 10 million of these and related models. Tesla is not the only customer.<p>This device isn&#x27;t enough for a full point cloud.  It doesn&#x27;t scan in elevation, just azimuth.  Some variants do have an upward-pointing beam in additional to the main forward beam, which is about 5 degrees in vertical.<p>There are automotive radars which scan in 3D[2], but Tesla&#x27;s is not one of them.<p>Small radars are rather blunt instruments.  You tend to get one point for each target, not lots of points. The beam focus isn&#x27;t that tight.  Tighter focus requires a larger antenna array.<p>[1] <a href="http:&#x2F;&#x2F;www.automotiveworld.com&#x2F;news-releases&#x2F;bosch-presents-new-radar-sensor&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.automotiveworld.com&#x2F;news-releases&#x2F;bosch-presents-...</a>
