Use this command to recalculate the velocity from the currently active Doppler spectrum.
Either all or a selection of the Doppler spectrum can be used.
The resulting trace can be output to a new trace, or replace the values in an existing trace. The existing trace must have the same sample rate as the source Doppler spectrum. Sections of an existing trace may be replaced enabling different detection thresholds to be used for different signal strengths in the recorded Doppler spectrum.
A modeless Threshold dialog control enables the threshold to be adjusted to the optimum level. Press the apply button to recalculate the velocity.
The Artifact Filter can also be activated to control the action to take for signal dropouts and noise spikes.
The method previously set in the Calculations | Velocity menu will be used.
