Targets:
The first ceiling echo is around 200 cm, which should be quite high versus the neighboring noise
floor. Using a lens will make this target peak thinner and higher and more easily detectable by the
CFAR operator. The next targets are around 260 cm, 410 cm, and 460 cm.
Due to the adaptive nature of the CFAR operator it might happen that if two targets are too near to
each other or are very different in magnitude, one of them is rejected (hidden) by the CFAR
operator, such a target may be hidden around 220 cm. Changing the target recognition settings
might help in this situation.
DC component:
There is some DC component on the left side. If this DC offset is high, it might trigger a false target
detection of the CFAR operator.
Clutter:
Around 290 cm to 330 cm there might be some clutter which is rejected by the CFAR operator.
