Since the 21st century, our highway transportation industry has presented a trend of rapid development, personnel and property casualties that caused by traffic accidents are also in a straight rising trend. Due to the illegal phenomena of such as speeding on the road, illegal stopping and so on, cause traffic accidents to occur continuously.

Nanoradar MR62 millimeter wave radar has the function of multi-lane ranging and speed measurement, which can accurately capture the position and speed of different targets in each lane within the detection range. At the same time, it is small in size, low in power consumption and easy to integrate, which can effectively reduce the probability of accidents and ensure road safety.

At present, the product is applied in traffic speed measurement, flow monitoring, road warning and other fields

MR62 Product Introduction

At present, the mainstream land-based detection radars in the market are installed in separate parts. The traditional radar is large in volume and cannot be integrated into other equipment to form an integrated structure. With the development of high frequency and high precision radar, radar modules began to be integrated into cameras, which effectively saved construction costs and increased market acceptance. The radar uses 60GHz frequency band to detect 32 targets at a distance of 100 meters in real time.

According to the Notice on the Issuance of Interim Provisions on Radio Management of Car Radar issued by the Ministry of Industry and Information Technology, the frequency of 76~79GHz is used for car radar, and land-based radar should avoid this frequency band. 60GHz is used for M62, and in order to avoid mutual interference problems (such as false alarm, shortened detection distance, missed alarm, etc.) that may be caused by installing multiple radars of the same frequency at an intersection, a 4-step wrong frequency function is developed. At the same time, in order to better adapt to the environment and reduce the interference caused by different weather and environment, a 4-step sensitivity function is developed.

MR62 Product Advantages

60GHz frequency band

Perfectly stagger the vehicle-mounted millimeter-wave radar 77GHz band, avoiding false alarms, shortened detection distance, missed alarms and other unnecessary problems caused by millimeter-wave radar interference in the same frequency band, ensuring the reliability of land-based radar use, while avoiding accidents caused by interference in the same frequency band with vehicle-mounted radar.

MIMO system

MR62 uses MIMO 3 transmitting and 4 receiving 12 channels integrated array antenna, its accuracy can reach ±0.5°, meanwhile, MR62 uses uniform array, which can suppress the appearance of gate flap and get more stable angle measurement effect.
