What is the limiting performance of PDV (really)?
The limiting performance of PDV is determined by power spectrum location resolution - The uncertainty principle overestimates error and peak fit confidences underestimates error. Simulations indicate that PDV is: (1) Inaccurate and imprecise at low frequencies; (2) Accurate and (potentially) precise otherwise; (3) Limiting performance can be tied to sampling rate, noise fraction, and analysis duration. Frequency conversion is a good thing. PDV is competitive with VISAR, despite wavelength difference.
