Threshold offset
The threshold offset is adjustable and defines the
distance in dB between the noise floor of the raw
FFT data and the threshold line. The processing in
the K-LD7 searches for raw targets that are above
Figure 9: Low vs. high threshold offset
this threshold line. The smaller the offset the more raw
targets will be found by the processing and the more
sensitive the sensor will be. A higher offset will reduce
the sensitivity and the number of raw targets.
Tracking and vibration suppression
The tracking filter features three different filter types
and an adjustable vibration suppression. The filter
type and the strength of vibration suppression can be
selected via the instruction set.
With the vibration suppression, it is possible to more
or less suppress targets that change their direction
quickly, with the disadvantage that it takes more time
to detect a target.
Base frequency
There are three channels available to adjust the base
transmit frequency of the sensor. This can be use-
ful if multiple sensors are transmitting in the same
area with the same base frequency to suppress the
generated interferences that can occur in such an
environment.
Filter type Description
Standard Standard filter type to track different targets like persons or cars
Fast detection Enables a faster detection of the target with the disadvantage to reduce the immunity against reflexions and other interferences.
Long visibility Filter with a high immunity against interferences and a high prediction of temporary lost targets
Table 5: Tracking filter types
The filter can only track one target up to a dis-
tance of 30m.
