Nanoradar 77Ghz Radar MR76 for Intelligent Transportation

 

MR76-T traffic flow radar uses 77GHz MIMO technology performs all targets in the scene Detection, able to eliminate stationary targets and various clutter resulting false alarms. Improved multi-target detection capability, The radar has high detection accuracy and can accurately measure , speed, distance, angle and other information of the moving target. The radar can detect 4 lanes and 64 targets at the same time
The distance, speed and angle information of the vehicle, the most The long-distance detection distance can reach 150 meters for the car.

 

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.
