The sensor\u2019s processor calculates how long it took for the waves to bounce back in order to determine:<\/p>\n<ul class=\"wp-block-list\">\n<li>Distance to object<\/li>\n<li>Speed of object<\/li>\n<li>Angle of object<\/li>\n<\/ul>\n<p>Millimeter-wave radar systems generally operate in frequencies between 76-81 GHz. Higher frequencies allow millimeter-wave radar systems to be highly accurate without needing to be too large.<\/p>\n<p>That\u2019s why you\u2019ll typically find millimeter radar sensors neatly tucked behind your vehicles bumper or grille.<\/p>\n<p>All of your vehicle\u2019s ADAS features including AEB, adaptive cruise control, blind-spot monitoring, and cross traffic alert operate using millimeter-wave radar.<\/p>\n<h2 class=\"wp-block-heading\">Why Modern Vehicles Rely On Millimeter-Wave Radar Technology<\/h2>\n<p>The downside to cameras\u2026<\/p>\n<p>They can\u2019t handle bright sunlight.<\/p>\n<p>Bad weather messes with lidar.<\/p>\n<p>But millimeter-wave radar can see through pretty much anything.<\/p>\n<p>It\u2019s no surprise that automakers have been speeding up production of millimeter-wave radar systems.<\/p>\n<p>S&amp;P Global estimates that Level 2 ADAS vehicles now account for 40% of worldwide vehicle sales. That number is expected to jump to 62% by 2032.<\/p>\n<p>If you\u2019re still thinking your shop won\u2019t be affected\u2026<\/p>\n<p>Think again.<\/p>\n<p>Not only are vehicles coming in with radar-based safety systems more often, but when these sensors become damaged or misaligned during a collision, they need to be recalibrated.<\/p>\n<p>In other words, collision repair sensor alignment is essential. Proper <a href=\"https:\/\/www.caliber.com\/services\/collision\/adas-calibration\">driver assistance systems calibration<\/a> ensures your vehicle\u2019s ADAS features function correctly.<\/p>\n<p>Some common applications of millimeter-wave radar include:<\/p>\n<ul class=\"wp-block-list\">\n<li>Auto emergency braking<\/li>\n<li>Adaptive cruise control<\/li>\n<li>Blind-spot monitoring<\/li>\n<li>Cross traffic monitoring\/alert<\/li>\n<\/ul>\n<p>As you can imagine, each one of these safety features rely on radar sensors functioning properly.<\/p>\n<p>When these sensors become misaligned during a vehicle collision, your shops ability to realign those sensors becomes mission critical to ensuring those safety features continue to work.<\/p>\n<h2 class=\"wp-block-heading\">Radar Sensors &amp; Collision Repair Sensor Alignment<\/h2>\n<p>What happens when your vehicle gets in a low-speed collision?<\/p>\n<p>The sensors can get knocked out of alignment.<\/p>\n<p>Many repair procedures have the potential to move radar sensors inching, including:<\/p>\n<ul class=\"wp-block-list\">\n<li>Bumper replacement<\/li>\n<li>Windshield replacement<\/li>\n<li>Suspension repairs<\/li>\n<\/ul>\n<p>But don\u2019t take our word for it.<\/p>\n<p>According to CCC Intelligent Solutions, calibrations are now requested on over 35% of all collision repair estimates.
