Input Value: Passes on the radar signal unchanged, so the total amplitude of each signal wave is recorded.
Level Above Threshold: Subtracts the Threshold value from the radar signal to isolate only the signal that exceeds the threshold.
Full Scale: Converts any signal that exceeds the Threshold essentially into a binary signal (i.e. either zero or the maximum value).
SD (Standard Deviation) Factor: A factor used to clean up the process data by using the standard deviation of the local threshold data.

Identify the Clutter.
Add a Threshold.
Add a Signal Gain (which is a multiplication of the signal, e.g. 25 x 2) or a Signal Offset (which is a fixed offset e.g. 25 + 20), or both:
Finally add a Signal Spread. For example, with a Signal Spread value of 1, if a clutter signal was 1 bin wide, then the spread would be 1 bin either side of the clutter signal:
...
Threshold (pwr): This sets the threshold above which the radar samples are considered to be clutter as opposed to noise. This threshold is relative to the median signal strength at each range.
