Diversity Radar Mode
In diversity radar mode four radar units are grouped into two pairs, which are mounted in a
way that two secondary range measurements are performed side by side separated by a
defined distance. The following features differentiate the diversity radar mode from the other
radar modes:
Suitable for ranges up to 500 m
Distance is always measured to the partner unit and not to passive objects
No clearance to reflective surfaces / objects required (see chapter 5.1; Fresnel zone still
needs to be free of obstacles)
If one of the two measurement paths fails, the system falls back to operation in
secondary radar mode and is therefore still available (error is indicated in diversity status
byte)
