Product description Test details

The AST-SMMW-200 millimeter-wave radar system is a very long-distance millimeter-wave radar sensor system with solid-state design and strong seismic capability. The measurement distance is 200m, which can detect motion by adopting a highly complex FMCW modulation mode The target distance, speed, with a high range and speed accuracy.
The AST-SMMW-200 has the functions of ranging and anti-collision, and has been widely used in auto cruise control (ACC), forward collision warning (FCW) and automatic emergency brake (AEB).
AST-SMMW-200 sensor CAN communication network to follow the ISO11898-2 specification, the communication rate of 500Kb/s.
