Announcement of 2nd Generation 77GHz Radar Solution Based on MMW
79GHz SAR Imaging, Object Detection Even in Weather Conditions and Low Light

Autoroad Technology and STMicroelectronics (hereinafter ST) jointly exhibited automotive radar solutions at the International Automotive Technology Expo recently held in Chongqing, China.

At Auto Tech 2017, Autoroad showcased modules and solutions incorporating ST’s advanced, fully integrated 77GHz MMW radar products and announced innovative, newly developed radar imaging technology using 79GHz Synthetic Aperture Radar (SAR).

Autoroad's 77GHz radar solution, the first to be developed in China, was launched on the market in 2015. What was showcased at the Chongqing Auto Show is a second-generation solution based on ST's MMW products.



ST's latest 77GHz MMW broadband radar IC is a highly integrated, compact solution based on a multi-channel architecture that provides excellent object recognition and resolution for Forward-Collision Warning, Adaptive Cruise Control, Autonomous Emergency Braking, and other safety functions in any weather condition.

In addition, Autorod has achieved a breakthrough in 79 GHz SAR imaging. Autorod demonstrated a new approach that combines distance resolution generated from broadband signals with azimuth resolution generated using relative vehicle movement to detect and recognize objects in weather conditions such as rain, snow, and smog, as well as under extremely low light conditions.

SAR technology implemented using ST's 79GHz RF front-end IC can generate high-resolution 2D and 3D images by utilizing the relative movement between the installed radar and the target. This enables the detection, recognition, location, and size estimation of vehicles, pedestrians, and other objects around the vehicle under all weather and lighting conditions.
