Kalman filter
o
The Kalman filter reduces the noise of the distance measurement output for standard
measurement setups with linear motion. For non-standard applications in primary
radar mode it may be advantageous to disable the filter.
Raw data output
o
Raw data can be provided by the unit for further analysis.
Raw data mode
o
Depending on the configuration the unit can provide raw ADC data, FFT spectra
and/or the configured threshold values.
Raw data rate
o
The raw data rate can be used the scale the amount of data which has to be
recorded. Data is sent every n measurements.
RX attenuator mode
o
The RX attenuator can be enabled when the received signal is too strong.
VGA value
o
The VGA value determines the power of the transmitted signal.
The LPR

-1DHP-200 in primary radar mode can either output the distance to the first or the
strongest valid target. A target is valid, if its signal level is higher than a set signal level
threshold level profile, which is segmented into 3 range zones (short range, mid range, long
range). The start and end positions of the 3 range zones and their corresponding signal
threshold levels can be configured individually with the settings described above. An
example of the radar target spectrum (target signal strength vs. distance) recorded in a multi
target environment is shown in where the window for valid targets defined by the range
zones and their threshold levels is marked green.
Targets outside of this window will be
ignored.
A change of the range zones and their threshold level settings is only necessary in a multi
target environment and should only be conducted by trained personal.
