3.7.1.4.1
Fog filter
The fog filter enables the device to eliminate unwanted echoes at close range. This
considerably lowers the probability of false activations at close range in fog.
Figure 17: Without the fog filter: objects are
difficult to detect through the fog due to reflec‐
tions.
Figure 18: Using the fog filter: objects can be
detected reliably because unwanted echoes
are screened out.
3.7.1.4.2
Echo filter
The echo filter screens out unwanted measurement data and signals caused by edge
hits, rain, dust, snow and other ambient conditions.
You can set whether the first, the last, or all five echoes are output.
The other pulses triggered by undesirable ambient conditions are not taken into
account.
