5.4 Radar Positioning Measurements
The typical procedure when measuring a radar position is as follows:
1. Start the R&S QAR to start the system and the software.
For more information about the functionality of the software, see Chapter 5.4.2,
"Graphical User Interface" , on page 72.
2. Park the car in front of R&S QAR.
See Chapter 5.4.1, "Test Setup" , on page 71.
3. Measure the DUT.
See Chapter 5.4.3, "Measurement" , on page 74.
4. Save measurement data.
See "Managing measurement results" on page 78.
5.4.1 Test Setup
For radar positioning measurements, the test setup consists of the R&S QAR and the
DUT, for example a radar module installed behind the bumper of a car. To measure the
position of the radar module, you simply park the car in front of the R&S
QAR. Make
sure to park the car at the correct position as indicated in Figure 5-20 to get valid mea-
surement results.
Figure 5-20: Test setup for radar positioning measurements (side view)
The optimal distance to the front of the car depends on the location of the radar mod-
ule relative to the radome's location on the car.
●
The distance between R&S QAR and radar module is between 60 cm and 80 cm.
●
The distance from floor to radar module is between 34 cm and 68 cm.
●
The offset of the radar module relative to the center of the R&S QAR panel is
14.5 cm to the right of the center of the panel.
