Technical principles
77GHz millimeter wave radar working principle and technical parameters
Working Principle of 77GHz Millimeter Wave Radar
77GHz millimeter-wave radar uses radio waves in the millimeter-wave band for detection. It measures the distance, speed, angle and other information of the target by transmitting and receiving the reflected waves between the radio waves and the target object. Compared with other sensing technologies, millimeter-wave radar has higher accuracy and stronger environmental adaptability, and can provide stable measurement data under various weather conditions.
Workflow:
-
Millimeter wave radar emits 77GHz electromagnetic waves
-
Electromagnetic waves are reflected after encountering the target object
-
The radar receiver captures the reflected wave
-
By calculating the time difference and frequency change between transmission and reception
-
Accurately measure the distance, speed and size of the target object
Schematic diagram of Virtual Aperture Radar (VAR) technology
VAR technology uses 4D detection to accurately identify target height information, which is crucial for height limit warning and vehicle size measurement.
VAR technology advantages:
-
Accurately identify multiple targets: vehicles, pedestrians, obstacles
-
High-precision height measurement: can accurately determine whether the vehicle is over-height
-
All-weather working ability: not affected by environmental factors such as light, haze, etc.
-
Multi-target simultaneous tracking: can monitor multiple moving targets at the same time

Application scenarios
Application of millimeter wave radar in various scenarios
Bridge height limit monitoring
A 77GHz millimeter-wave radar is installed at the entrance of the bridge to monitor the height of passing vehicles in real time. When an over-height vehicle is detected, the system will immediately sound an alarm to avoid vehicle collisions with the bridge, effectively ensuring traffic safety and bridge structure safety.
Logistics and freight height control
In logistics centers and freight stations, millimeter-wave radar can be used to monitor the height of loaded goods to ensure that they meet the height limit requirements for road transportation and avoid safety hazards and fines caused by over-height transportation.
Intelligent parking lot management
Installing millimeter-wave radar at the entrance of the parking lot can guide vehicles according to their size, realize the partitioned parking of large and small vehicles, and improve the utilization rate and management efficiency of the parking lot.
Tunnel safety monitoring
Installing millimeter-wave radar at the entrance of the tunnel can identify over-height vehicles in advance, prevent collision accidents after vehicles enter the tunnel, and ensure tunnel traffic safety.
Installation and debugging

Installation guide
To ensure optimal performance of the 77GHz mmWave radar, follow these installation recommendations:
-
Location selection: Choose a location that can cover all passing vehicles
-
Antenna direction: Make sure the radar antenna faces the detection area and is not blocked by any metal objects
-
Avoid interference: Keep away from signal antennas, large electrical equipment, motor actuators, etc.
-
Protective measures: Avoid applying glue on the radar antenna surface. If a protective cover is required, choose an area with a smooth curved surface
