AST-SMMW-30 is a very cost-effective short-range K-band millimeter-wave radar sensor system . It has a monitoring distance of 30 meters and adopts a high-complexity FMCW modulation mode. It can detect the distance, speed and angle of moving targets, and has high ranging and speed measurement accuracy. AST-SMMW-30 has functions such as blind spot detection (BSD), lane change assist (LCA), and open door warning (EAF).
The CAN communication network interface of the AST-SMMW-30 sensor complies with the ISO11898-2 specification and has a communication rate of 500Kb/s. It has a universal external communication interface for easy integration with the host computer or other ADAS modules.
