Check Target Signal Strength
:
Typical Real Time Chart Recorder View of “Intersection Mode”
Five targets are shown and are stationary in this view. Horizontal target lines means
distance to target is not changing over time. You may enable histogram to show all
observed targets stacked up on the left. This will provide better statistical data for lane
configuration. You should also enable the “Show RSS (received signal strength)
checkbox to view the signal strength of the return signal from the visible targets.
For every target detected the histogram grows by one pixel when the target is no longer
being tracked.
Stationary targets will meld into the background clutter and disappear from view with the
“Background Clutter Compensation” time constant. Thus it’s very important to set the
clutter time constant to a value that is at least 5 to 10 times longer than the normal
expected presence time of targets in front of the radar.
Targets are plotted in real time as red lines and
scroll from the right to the left.
Long lines as shown represent stationary
targets (this plot was taken inside a room.
Some of the top targets are double reflections
from walls and corners).
Range can be read off the scale on the right.
Alternatively click on the target for a range
reading on your screen or right click to access
plot zoom features to get a more accurate
reading.
Check “Show RSS” to show the
target Receive Signal Strength. 3 or
more solid bars out of 5 represent a
good signal.
You should adjust the
radar pointing if you get 2 or less
bars to a desired target
.
A very weak target. Only 5
empty RSS bars.
Will be first to fade away
into background clutter.
