Figure 4-5: AREG Radar Power Indicator
●
Green
RX power is in linear range.
●
Yellow
RX power is strong, non-linear effects can occur
Reduce input power, for example by enlarging the airgap.
●
Red
RX power is in a range, where the receiver is in saturation.
Enlarge the airgap or reduce radar power.
This can also be caused by too much gain in the R&S
AREG100A (i.e. negative
base attenuation setting) in conjunction with reduced AREG TX-to-RX isolation,
leading to signal oscillation.
TX-to-RX isolation is lower for monostatic AREG setups, and if metal objects or
signal reflectors are placed closely in front of the AREG antennas. Remove or tilt
these objects and / or turn up the base attenuation setting of the AREG to reduce
the risk of oscillation.
●
Grey
No or very weak RX power is detected.
Make sure the radar under test is working, located in a useful distance (i.e. airgap)
from the AREG, and pointing at the AREG antennas. Also pay attention to the cor-
rect polarization of the radar under test: The AREG antennas are vertically polar-
ized if the control and IF connectors of the frontend module point upwards.
