Highly integrated and compact millimeter-wave (mmWave) radar chips have come into being with the development of the CMOS and AiP technologies, and are now increasingly applied to various scenarios.

· Smart Home
In smart-home scenarios, mmWave radar boasts accurate detection of people indoors and advantages such as security, low cost, and no privacy invasion. This new approach has broken through the limitation of traditional detection methods including infrared and visual detection.

· Smart City
mmWave radar, applied in security and surveillance, smart transport and barrier gates system, has become an integral part of a smart city. 

· Industrial Automation
The precise detection capability of mmWave radar can help robots and UAVs bypass and even avoid obstacles.
