2、CSR-IM Multi-Target Radar Installation Notes
CSR-IM multi-target radar mainly snapshots aim at the driving vehicles in multi-lanes at the same
time; usually the radar is fixed on the middle position of multi-lanes in width direction. That is the middle
position of portal frame above the lanes. (see detail in figure2.1, take 3 lanes as example）;

Figure 2.1: CSR-IM Multi-Target Radar Installation Position-Planform
Pay special attention to assure the radar’s positive side points to the direction of the lanes, and the
port of radar cable points to the ground (face down) during installation; as shown in figure 2.2.
Figure 2.2 the Cable Terminal of Radar Points to The Ground
The radar side installation method is as shown in figure 2.3, the radiating area of the radar beam is a
region of lanes; the width of the region that the beam covered is related to the central position of the beam
etc. The width of the region that the beam covered is around 10m, while the beam center of typical radar
is at 24m.
Figure 2.3: CSR-IM Multi-Target Radar Installation Position—Side View
The installation declination angle under different installation height and triggering distance refer to
table2.1~2.3. For obtaining the best result, the installation declination angle will be different due to
different driving direction in monitoring lanes. The reference value under different condition is shown in
table 2.1~2.3. The related installation of declination angle value can be checked in table 2.1~2.3 refer to
predetermined radar height, trigger distance and the driving direction condition in monitoring lanes. The
value of declination angle can be estimated by linear interpolation if the height and trigger distance is

between the two values as below.
Table 2.1 Radar Installation Reference of DeclinationAngle (Monitoring the Going Lane only)
Table 2.2 Radar Installation Reference of DeclinationAngle (Monitoring the Coming Lane only)
Table 2.3 Radar Installation Reference of Declination Angle (Monitoring both of Coming and Going Lane)
In the latest upper computer software, the reference value of the radar installation declination angle
will be inputted automatically after the triggering distance and installation height are inputted, dispensed
with the table check and calculation. As shown in figure 2.4
Figure 2.4: Calculate the reference installation declination angle according to the installation height and
triggering distance at once
In addition, in order to enlarge the application scopes of monitoring and lower the standards of
installation, the actual installation position of the radar could deviate from the center of the overall lanes
and the furthest distance could be 3m away from the outermost lane.
As shown in figure 2.5, the radar could be installed on any position deviated from the center of the

(9) Setting the radar parameter
(a).Choose the direction according to the actual driving direction of vehicle which is monitored. The
default direction is coming direction, as shown in figure 3.11.
Figure 3.11: Direction Setting
(b).Choose the number of lanes according to the actual monitoring lanes, and set the width of each lane
according to the actual width of lane. For example, if the width of lane 1 is 3.5m, set the width of
lane 1 to 3.5m, and each lane needs to be set. Click “enter” to send out the command after inputting
all the parameters. Setting is as shown in figure 3.12.
Figure 3.12: Setting of Trigger Mode and Width of Lane
(c). Installation setting. Set the triggering distance to 24m, and the installation height depends on the
actual situation (for example, the height value should be set to 7.5m when the radar needs to be
installed on portal frame with the height of 7.5m).
(d). Horizontal offset. For example, the value will be 0 when the radar is installed on the middle position
of the second lane, but the value needs to be changed to 3.5m when the radar is installed on the
middle position of the third lane (assume the width of lane is 3.5m). Change the horizontal
deviation distance according to the radar installation position, as shown in figure 3.13 (c) and
(d).
Figure 3.13: Radar Installation Setting
(e).Deflection angle and declination angle. Software can figure out the related reference deflection angle
and declination angle automatically after finish setting installation height and horizontal deviation
distance, as shown in figure 3.14. Radar will be installed according to the reference deflection angle
and declination angle.

Figure 3.14: install radar deflection angle and declination angle according to the reference value
(f).after finish setting above parameter, click button” all send out” to finish sending parameter to radar,
and click button “save” to save the current setting. As shown in figure 3.15.
Figure 3.15: Send out all radar parameter and save
(g).for radar installation, declination angle can be set exactly by electronic instrument, meanwhile the
offset of declination angle does not affect the performance of radar greatly .while it is difficult to
set the deflection angle in left and right direction exactly by electronic instrument and the deflection
angle in left and right direction affects the performance of the radar greatly, so the radar calibration
needed to be implemented to correct the installation error. Take figure 3.16 as example, the
suggested radar deflection angle is 16.3°, declination angle is 14.5°. Assuming the triggering
distance is 24m, the installation height is 7.5m, the horizontal deviation is -7.0m, at this point , the
radar will be installed by deflection angle 16.3°,declination angle14.5°(certainly , a difference may
exist between real value and expect value)
Figure 3.16: Radar deflection angle car passing calibration
After that ,using the car passing calibration function when vehicle are passing by, the radar will
implement data collection and calculate the deflection angle then feedback the angle value .
Figure 3.17: Radar deflection angle calibration and feedback
As shown in figure 3.17, the corrected value is 16.7°, differs by 0.4°from the reference value
(16.3°), according to the regulation, when corrected value differs by more than 1°from the reference
value, radar need to be adjusted and calibrated repeatedly till the difference is within ±1°.

(h). After the radar is calibrated correctly, it can be estimated that whether the target display coincided
with the real traffic situation or not on target simulation interface.As shown in figure 3.18
Figure 3.18: Target simulator interface
(i). Click advanced options to display advanced options dialog box.As shown in figure 3.19.
Figure 3.19: click advanced options to display advanced options dialog box
(j).In advanced options dialog box, you can set velocity range，distance range and other technical
parameters, as shown in figure 3.20. When you have set relevant parameters successfully, it will
display in status display column as shown in figure 3.21.
Figure 3.20: check cart mode and click ok button
Figure 3.21: log in status display column
(k). The radar target display runs well, it means no display omission (no lane display error or other error),
estimated by observing the target display in target simulation interface. Choose the snapshot lane, in
the output setting column which is used for controlling camera snapshot, then click “debug finished ,
connect to camera” button, then radar is ready for triggering camera to snapshot, as shown in figure
3.22.

Figure 3.22: output setting of radar control camera to snapshot
(l).After the setting of snapshot and connection to camera successfully, button “debugging finish / connect
to camera” will be changed to “return to debugging the mode”, at this moment, the setting of the radar
cannot be modified, if the camera snapshot result is not perfect, click button” return to debug mode”
to return to debug mode, as shown in figure 3.23
Figure 3.23: click “return to debug mode” button to return to radar debugging mode

4、Key points of CSR-IM multi-target Radar Debug
Operator first time implement multi-target radar installation should pay attention
to the following key points and thoughts:
1. make sure the radar installation up-down pitching angle (declination angle) and left-right pivoting
angle(deflection angle) are within proper range, so that radar beam cover the monitoring lanes evenly；
Cover the region where nearby the radar trigger area to assure radar can detect and monitor vehicles in
lanes efficiently, realizing vehicle recognition correctly, speed-measurement positioning precisely and
triggering camera to snapshot.
Modifying the pitching angle and pivoting angle of radar will affect the region the radar can cover.
As shown in figure 4.1, the radar radiate position will be changed as changing radar up-down pitching
angle, in normal condition, the region that the radar beam cover is where nearby the triggering distance.
Figure 4.1: radar pitching angle modify reference sketch map
As shown in figure 4.2, the radar radiate position in width direction will be changed as changing radar

horizontal pivoting angle, in normal condition, the radar beam should cover the monitoring lanes evenly.
Figure 4.2: radar horizontal pivoting angle modify reference sketch map
In a word，the ultimate purpose of installation modify, is assure the radar beam radiate the region
nearby the radar trigger area(neither higher nor lower), the radar beam cover the monitoring lanes
evenly(neither too left nor too right), as far as possible .
On upper computer, two kinds of target vehicle display mode can be used（1）continuous mode: it
means radar send data to upper computer continuously and upper computer display target vehicle
continuously, just like forming a movement locus（2）contact mode: it means radar send data to upper
computer only if target pass through the trigger line, just like number counting of vehicle.
In detail performance standard, for 3 lanes monitoring, if no display omission after 60 vehicles pass
by continuously ,debugging and calibration can be considered to be finished .for 4 lanes monitoring, if
no display omission after 80 vehicles pass by continuously ,debugging and calibration can be considered
to be finished.
After the debugging and calibration, connect the radar to camera, refer to table 3.3

Plenty of unusual conditions which lead to the failure of debugging may arise during the debugging
the procedure of CSR-IM multi-target radar, meanwhile the actual condition may be not consistent with
condition in debugging software. Therefore the unmatched condition should be changed to standard
condition in upper computer, subject to condition in upper computer, as for as possible, in order to
debugging the radar in relevant ways, when debugging radar by upper computer.
5.1 Special cases analysis: fence /isolation belt in lanes
If fence/isolation belt exists in lanes，the width of fence / isolation belt should be added to the width
of the neighbor lane. As shown in figure 5.1, in the condition of both way four lanes, width of the fence
/ isolation is 2m, in this case, half of the width of fence should be added to the width of lane 2, the other
half should be added to lane 3, the width of lane 2 is changed to 4.5m from 3.5m, the width of lane 3 is
changed to 4.5m from 3.5m; the total width of lanes include width of fence and width of all lanes.
Figure 5.1: fence/isolation belt in lanes width modify sketch map
5.2 Related Malfunction and Solution of Debugging
1．The Situation of Missing Vehicles in Multi- Lanes at the Same Time
Analysis：Refer to figure 4.1. The reason why the situation happens is the radar pitching angles up and
down in the vertical direction are too large or too small, in consequence, the radar beam radiating region
will be not nearby the triggering distance region, and the radar signal of vehicle will be too weak in each
single lane, and finally the situation of missing vehicles in multiple lanes will happen.
Solution of Debugging：Modify the pitching angle up and down of the radar to make the area the radar
beam covered near the triggering distance.
2．The Situation of Missing Vehicles in Single Lane
Analysis: Refer to figure 4.2. The reason why the situation happens is the deviation of the radar pivoting
angles left and right in the horizontal direction are too left or too right, in consequence, the beam of the
radar will not radiate every single lane evenly, and the lane will not be covered effectively, and the signal
of the radar will be too weak, and finally the situation of missing vehicles in single lane will happen.
Solution of Debugging: Modify the pivoting angle left and right of the radar to make every single lane
covered by the beam of radar evenly.
3．The Situation of Dividing Lanes Wrong: vehicle is divided to wrong lane
Analysis: The reason whythe situation happens is that the radar is not calibrated correctly, or the parameter
of the installation position is not exact enough, which leads to the lanes false distinguished of monitoring
vehicles by the phase.
The Solution of Debugging:
(1) First of all, confirm whether the radar installation position parameter input is right or wrong, whether

the actual deviation is too large or not. If yes, input the correct parameter. Modify the offset of the radar
properly (the position that the radar installed on the portal frame radar).
(2) If the radar installation parameter input is correct, then the result might be caused by the calibration
error, then the radar needs to be calibrated again.
