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 transmis-
sion loss measurements, the R&S
QAR provides an intuitive and powerful way to eval-
uate how radomes and bumpers influence the radar performance.
The R&S
QAR consists of a panel that contains the measuring electronics like trans-
mitting and receiving antennas. It also contains a PC with dedicated software to oper-
ate and control the measurements.
●
Radome measurements
The basic configuration enables you to measure the reflection of a radome.
The high resolution of the resulting images enables you to identify even the small-
est disturbance in the radome. The R&S
QAR uses the frequency range between
72
GHz and 82
GHz. 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.
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.
●
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.
