Lens Performance

The transmitted electromagnetic
waves from the Acconeer
sensor has different divergence
for the E-plane and H-plane.
When mounted in front of the
sensor the lenses affect the
signal strength as well as the
spread of the signal.
The expected performance for
maximum gain and half power
beam width (HPBW) can be
found in the table below.
Max Gain. (dB
Free Space 0
Cover -0.15
Lens Position D1
HBL 5.8
FZP 5.7
* The dB gain is the radar loop gain (Tx + Rx gain) relative to a free-space measurement.
