Methods to compute the along-beam velocity fluctuation:
- If using burst sampling, calculations are done over the length of the burst or some sub-period over which the turbulent flow statistics can assumed to be stationary
- If using continuous sampling, calculations are done over segments with a duration over which the turbulent flow statistics can assumed to be stationary
- For each data segment consisting of N profiles, the turbulent fluctuations are calculated separately for each beam and bin by either:
- The mean over the data segment
- A linear detrend of the segment
- A low pass filtered signal
