Description


Car Front Sensor Collision Warning


 


When the vehicle is running in front of a sudden obstacle and other emergencies, the human response time is about 660 milliseconds, while the radar collision avoidance system response time is less than 50 milliseconds, radar is 13 times faster than people! Radar is an intelligent sensor to prevent vehicle from collision. System with radar technology can automatically detect obstacles and avoid collision of vehicles, pedestrians by alarming or braking, making the driving safety from "passive" to "active".


 



 


Radar features:


*Work in 77GHz-ISM-Band for the detection of moving objects


*Compact size (140x70x35mm)


*Accurately measure the direction, range, velocity and angle of moving targets


*Protection class IP67


*Hige detection rate

Radar description:


The MR76 USES 77GHz high-frequency electromagnetic waves to analyze the surrounding environment. The reflected signal is output as an object after several steps of processing. Objects are information about the location, speed and signal strength of radar reflections that are calculated and output once every period.
