» Size of the obstacle
The measurement resolution decreases with rising distance between the obstacle and
the measurement device. This is due to the fact that the size of the laser spot gets
bigger with increasing distance.
Figure 12 shows the minimum object size with changing distance. It is important to know
that the values in this diagram are determined with the least possible remission. That
means it describes a “worst case scenario”.
Figure 12 Minimum object size
These diagrams should only provide an approximate idea of the object sizes that might be
considered when integrating a radarTOUCH and are usually more pessimistic than the reality.
In the end, only practical tests can deliver reliable answers.
