R&S QAR tour
3 R&S QAR tour
The R&S QAR is a millimeter wave imaging system operating in the frequency band of
automotive radar sensors. With its support of spatially resolved reflection and transmission loss measurements, the R&S QAR provides an intuitive and powerful way to evaluate how radomes and bumpers influence the radar performance.
The R&S QAR consists of a panel that contains the measuring electronics like transmitting and receiving antennas. It also contains a PC with dedicated software to operate and control the measurements.
●
Radome measurements
The basic configuration allows you to measure the reflection of a radome.
The high resolution of the resulting images can identify even the smallest disturbance in the radome. The R&S QAR uses the frequency range between 74 GHz
and 79 GHz to measure the reflection. Therefore, any faults visible in the millimeter
wave image directly correlate to the performance of the radome in combination
with a radar sensor.
An optional transmitter module (R&S QAR-Z10) extends the functionality of the
R&S QAR to measure the transmission loss of a radome. For the transmission, the
R&S QAR uses the frequency range between 72 GHz and 82 GHz.
Additional equipment like an optional platform (R&S QAR-Z20) on which you can
mount the R&S QAR, or a table for the device under test (DUT mounting table,
R&S QAR-Z50) are also available.
The default setup uses all 12 measurement clusters built in the R&S QAR to analyze radomes. With an additional software option (R&S QAR-K50), you can unlock
single cluster measurements that only use one of the built-in clusters.
●
Bumper measurements
An optional reference reflector (R&S QAR-Z60) is available to measure the mean
transmission loss (attenuation) caused by a bumper.
The reflector measures the attenuation in 102 points and therefore enables you to
evaluate the homogeneity of the bumper painting and its overall radar penetrability.
●
Radar positioning measurements
The basic configuration enables you to measure the position of the radar in the car
and compare it with the theoretical position indicated in the manufacturer's CAD
files.
You can set acceptance limits and verify in a few seconds if the radar is correctly
positioned.
Additional equipment like an optional platform (R&S QAR-Z21) on which you can
mount the R&S QAR, or a verification set (R&S QAR-Z42) are also available.

Main power supply
The main power switch contains an RCD (residual-current device) that protects the
internal power circuit of the R&S QAR. If the RCD detects electrical anomalies, it will
switch off automatically the R&S QAR.
For more information about supplying the panel with power, see Chapter 4.4, "Switch-
ing the R&S QAR on and off", on page 34.
Establishing a ground connection
WARNING! Risk of electric shock. If the voltage or frequency are greater than
1.
230 V or 50 Hz, the leakage current of the R&S QAR can be above the limits and
can cause personal injuries from an electric shock.
In that case, a protective ground connection must be established before connecting
the R&S QAR to the mains supply.
● 200 V to 230 V AC and 50 Hz
No additional protective ground needed.
● 230 V to 240 V AC or a frequency greater than 50 Hz
Additional protective ground needed.
Exception: The following two 60 Hz AC distribution systems are tested and
work without an additional ground.
For the separate protective ground, you need a green/yellow ground wire with a
cross section of at least 4 mm2 in addition to the main protective earthing terminal.
The ground wire must be connected permanently to the ground terminal on the
side of each R&S QAR panel and earth.
The ground terminal is located on the back of the scanner. Connect the terminal to
the protective grounding system of the building or room where the scanner is
installed.

Verify that the top of the reflector pins are parallel to the R&S QAR front by using,
for example, a spirit level. Check the lateral distance by performing the verification
described in Chapter 5.3.5, "Verification", on page 71.
2. Align the reference reflector with a spirit level.
The top of the reflector pins have to be parallel to the front side of the R&S QAR
panel.
3. Screw the reference reflector to the stand with the Torx wrench.
4. Normalize the measurement to verify the position of the reference reflector.
For more information about normalizing the measurement, see Chapter 5.3.3.1,
