79GHz SAR imaging radar (synthetic aperture) system adopts the highly integrated, high-bandwidth RF front-end chips that provide the high-resolution imaging function in addition to its detection function. In terms of both distance resolution and azimuth resolution or refresh time, it can meet the high-end requirements of sensors by L3 and above automated driving technology.
The SAR imaging radar could launch large broadband signal to ensure high range resolution. Radar is installed on one side of the automobile to take advantage of automobile movement to compound equivalent long aperture and ensure high azimuth resolution. Finally, combining range and azimuth resolution, it will present HD two-dimensional radar images.
