1Product Introduction
Overview1.1
Aiming at traffic applications, the Radar adopts brand-new software and hardware technologies to
measure the distance, speed, angle and range of multiple targets. Based on the measured
information, the Radar reports accurate trigger signals to the camera.
With FMCW and MIMO technologies, the Radar realizes faster and more accurate measurement of
distance, speed and angle. In addition, the embedded tracking algorithm makes the Radar especially
suitable for scenarios with heavy traffic flow, such as multiple-lane check points and traffic
information collection, ensuring effective triggers of all targets.
Features1.2
Center mount and side mount available.
Covers up to 4 lanes horizontally.
Reports triggering information including lane number, vehicle speed and vehicle length.
Detects and keeps track of vehicles within the range from 15 m–100 m.
Adjustable trigger distance from 20 m–55 m with the accuracy of 1 m.
Configurable lower limit of trigger speed.
Advanced MIMO/DBF signal processing technology.
100 Mbps Ethernet and RS-485 communication ports.
Automatic azimuth angle calibration makes installation and debugging easy.

3Radar Installation
Installation Requirements3.1
Make sure that the installation environment is free of blockage and electromagnetic
interference.
Do not install 2 devices that share the same frequency (or same model) at one place.
Avoid metal reflective objects, for example, advertising board, in the FoV of the Radar.
The recommended installation height is 4 m–8 m.
Installation Position3.2
3.2.1 Adjusting Azimuth Angle
The azimuth angle refers to the angle between the normal line (0 deg) of the Radar and the direction
of moving vehicles.
When the normal line (0 deg) is on the left side of the lane line (axis y), the azimuth angle is positive;
when the normal line is on the right side, the angle is negative.
Azimuth angleFigure 3-1
The Radar supports 4 lanes at most.
3.2.2 Adjusting Elevation Angle of Radar
The elevation angle refers to the angle between the normal line of the Radar and the horizontal line
(road surface).

User’s Manual

Elevation angleFigure 3-2
When the Radar is facing down, the elevation angle is negative; when the Radar is facing up, the
angle is positive.

4.2.1 Setting Sensitivity and Lane Direction
You can set the sensitivity of the Radar and lane direction.
Set sensitivity and lane directionFigure 4-5
Sensitivity: The detection sensitivity of the Radar. 7 (default) is the highest level.
Dir: Select the lane direction from Come,Go and Double.

User’s Manual

There is no need to set the lane direction again under the lane parameter when setting Dir
to Come or Go.
You need to set the lane direction again under the lane parameter when setting Dir to
Double. Refer to "4.2.5 Configuring Lane Parameter" for details.
4.2.2 Setting Installation Parameters
Set the installation parameters based on the actual installation position of the Radar.
Installation parametersFigure 4-6
Height: The distance between the Radar and the ground. Set according to the actual installation.
Azimuth: Azimuth angle configuration. It can be automatically or manually calibrated. For
details, see "3.2.1 Adjusting Azimuth Angle".
The deviation between the set value and the actual value cannot exceed 10 deg. Otherwise, the
automatic calibration will fail.
Elevation: Set according to the actual installation. For details, see "3.2.2 Adjusting Elevation
Angle of Radar".
4.2.3 Reading Angle Alignment
When a vehicle travels normally inside the lane, the Radar collects the vehicle course angle and
calculates horizontal angle alignment data.
You can get the data by clicking Read under Setting > Read Ang.
Angle alignmentFigure 4-7
To get the data under different situations, you can do one of the following:
Test during normal traffic flow
When there are about 50 vehicles passing by, the software can calculate the angle alignment
value. Click Read, if the returned data is 0, wait for more vehicles to pass and then check again.
Test when the road is closed
When a road is closed, you can test the Radar by driving towards it in each lane more than 5
times. Ensure to maintain a speed over 30 km/h, and cover a distance of 100 meters to the Radar.
Multiple vehicles can be driven at the same time.

User’s Manual
13
The angle alignment data can be affected by traffic flow and vehicle track. Low traffic flow or too
many vehicles changing lanes can impact the result.
Angle alignment reading is mainly used in situations where the Radar is installed on the road
center. If the Radar is installed on sides, we recommend calibrating manually.
4.2.4 Setting Velocity Shift
To eliminate deviations between the measured speed and the actual speed, you can adjust the
Velocity Shift. It is 0 by default.
For example, the speed measured by the Radar is 62 km/h, and the Velocity Shift is -2 km/h, the final
speed is 60 km/h.

Parameter Description
Num The number of lanes that the Radar actually detected (up to 4).
Width Lane width. Only adjustable when Group mode is enabled.
Group
Enable the function, the software calculates lane parameters automatically
based on the start XL value, lane width and lane number.
Disable the function, you need to set the lane parameters manually.

User’s Manual

Parameter Description
XL(m)/XR(m)
Under the coordinate system of the Radar, the coordinates of the left/right lane line.
Negative value means the lane line is on the left side of the Radar and positive value
indicates the lane line is on the right.
Distance Detection distance. Only when a vehicle passes the line, can the Radar detect it.
Recommended range: 20 m–55 m.
Velocity The lower limit of the speed which the Radar can detect.
Direction Select lane direction when the Dir is set to Double.
Group Configuration
When the lanes are distributed evenly with the same width, you can enable the Group function. You
can only enter the lane width and the first XL value. The software will calculate the rest.
Single Configuration
When the lane width is not the same, or during other special situations where you need to enter the
XL and XR value for each lane. Disable Group, and the Width value is invalid.
We recommend enabling Group function when lane width meets the requirements.
Vehicles within the monitoring range will trigger the Radar to report to the camera through
RS-485 when both Distance and Velocity are exceeded.
4.2.6 Exporting Log
You can view the log and analyze the vehicle trigger information.
Operation logFigure 4-10
Select Output, and the software generates a .csv file containing vehicle triggering logs under
the default path displayed next to Output.
Clear Output, and vehicle triggering logs will not be saved to local.
Cancel selecting Output in advance. Otherwise you might not be able to view the logs in local
storage.
