3.3.3 Target-Timeline
The ‘Target-Timeline’ in Figure 25 shows the magnitudes of past targets. The x-axis shows the
distances of the targets and the y-axis shows the magnitudes of the targets in dB. The z-axis shows
the timeline of the data. Older values move to the back (higher z-values).
3.3.4 Spectrogram
The ‘Spectrogram’ shown in Figure 26 is another time dependent display of distance data.

3.3.5 Options
In the ‘Options’ menu, you can choose the coloring of the data between:
Magnitude
Range / target number
Phase angles (the phase angles are only colorized if the magnitude is larger than -120 dB
and when the Phase-frame transmission is enabled in the ‘System Configuration’ Tab)
No coloring
Coloring examples are shown in Figure 27 to Figure 30. There is also an additional option to
display phase markers above the detected targets. These markers show the phase angle of the
detected target. The phase angle is very sensitive to slight changes of the target distance within
one distance bin. It can be used to display relative motion in the µm range.
