Closest Algorithm
When the Closest algorithm is selected, RangeGuard bases its range measurement on the
shortest range peak in the reflected signal, within the Range Limits and above the Signal
Threshold. For this algorithm the Signal Threshold is fixed at 20dB above the nominal noise
floor.
The measured range is indicated on the Profile Plot by a vertical red line:
