Typical Real Time Chart Recorder View of “Highway Mode”
Targets observed in the last 5 seconds show up as red tracks while older targets that have
already scrolled off the screen are contributing to the height of the blue histograms on the
screen left. As can be clearly seen from the histograms, traffic has created four clearly
defined groups. Each group corresponds to a lane on the four-lane highway. Defining
lanes is as simple as drawing them around the histogram peaks as shown in the next
section.
Also note excellent signal strength from each of the shown targets. Each red track (a
target) has at least 3 or more filled “RSS” bars. Lower signal strength may indicate a
problem with radar installation and pointing.
Typically, for a given target length and speed, further targets will result in longer tracks
due to the beam diverging as it propagates away from the radar. This can be seen on the
example screen shot above.
Similarly, faster targets, all other things being the same, will result in shorter tracks.
Enable “Show Histograms” to
observe where targets are
appearing on the range plot.
This will help you define lanes.
