Automatic emergency braking (AEB), adaptive cruise control, blind-spot monitoring: behind all of them sits the same thing, a millimeter-wave radar working at 76–81 GHz.</p> <h2 id="why-7681-ghz">Why 76–81 GHz</h2> <p>Early automotive radars used 24 GHz; regulators and industry worldwide then moved almost in lockstep to 76–81 GHz, and the physics is straightforward. <strong>The wavelength is about 4 millimeters, so antennas can be made tiny</strong> — hiding them behind the emblem or bumper is trivial. At the same time the available bandwidth of 4–5 GHz delivers <a href="https://www.counteruavradar.com/en/knowledge-base/what-is-radar-resolution/">range resolution</a> in the centimeter-to-decimeter class: separating two cars driving abreast in one lane, or telling a guardrail from a stalled vehicle, is exactly what that bandwidth buys. The application lists standards bodies such as ETSI have drawn up for this band read like today&rsquo;s driver-assistance catalog: obstacle detection, Stop&amp;Go, blind-spot detection, park assist, pre-collision.</p>
