Defined monitoring area
•
A monitored area (
region of interest)
is defined in the field of view of the radar sensor.
The monitored area must be completely inside the field of view of the sensor.
•
The monitored area determines which radar measurement points must be taken into
account by the AOS301-WWD. Only those measurement points which are in the defined
monitoring area are evaluated.
