Troubleshooting
5.1 Target not recognized
A common trouble with Radar sensors is the misalignment of the sensor parameters to the
application. There are too many different parameters which can be optimized, to give a one-fits-all
setting from the beginning.
5.1.1 Too many targets -> CFAR doesn’t work
No targets detected although there are
plenty of targets around 2m.
If there are too many targets adjacent to each other in the field of view, the CFAR operator may
treat those targets like noise floor and calculates an envelope around those targets. Increasing the
number of guard cells may help in such a scenario.
