Detection settings
Detection filter
The last processing step in the K-LD7 generates a
detection output based on a set of adjustable para-
meters. The information about the detection is avai-
lable in the DDAT structure or on the digital outputs.
The parameters are all located in the radar parameter
structure which is described in detail in chapter Para-
meter structure on page 17.
The detection area of the sensor can easily be limited
with these parameters and allow the user to generate
very specific detections without the need of an advan-
ced signal processing.

Affected
data packets Description
Min. / max. detection distance DDAT Used to limit the detection area to a minimum and maximum distance. Detection is only generated if the
distance of the target isbetween the minimum and maximum detection distance limit.
Min. / max. detection angle DDAT Used to limit the detection area to a minimum and maximum angle. Detection is only generated if the
angle of the target is between the minimum and maximum detection angle limit.
Min. / max. detection speed PDAT, TDAT, DDAT Used to filter out slow or fast targets. Detection is only generated if the speed of the target is between
the minimum and maximum detection speed limit.
Detection direction PDAT, TDAT, DDAT Used to limit the detection by the direction. It is possible to detect only approaching or receding targets
or to allow both directions.
Range threshold DDAT Used to define a threshold for the range flag in the DDAT structure.
Target distance > range threshold DDAT range flag goes to low
Target distance < range threshold DDAT range flag goes to high.
Angle threshold DDAT Used to define a threshold for the angle flag in the DDAT structure.
Target angle < angle threshold DDAT angle flag goes to low
Target angle > angle threshold DDAT angle flag goes to high.
Speed threshold DDAT Used to define a threshold for the speed flag in the DDAT structure.
Target speed < speed threshold DDAT speed flag goes to low
Target speed > speed threshold DDAT speed flag goes to high.
