Radar systems are typically associated with military aircraft flying at high speed, but they have quickly made their way to civilian roadways and into commercial automobiles. Millimeter-wave (mmWave) radar systems are being integrated into new vehicles as part of advanced driver-assistance system (ADAS) electronic equipment for safer driving experiences. While fully autonomous, “self-driving” vehicles may still be a few years away, ADAS functions such as blind-spot detection and collision avoidance protect many drivers now. Low-power, high-frequency radar detection is vital to making it all happen, ultimately creating a safer driving experience.
