F. Andreucci et C. Camporeale, ON DOPPLER ESTIMATORS PERFORMANCE LOSSES IN THE PRESENCE OF NOISE ANDEQUIVOCATION, IEEE journal of oceanic engineering, 19(4), 1994, pp. 630-635
Doppler estimation accuracy for current profiling is discussed, with c
omparison with the Cramer-Rao bound (CRB). The apparent decrease in es
timation accuracy at low SNR is introduced by the estimate equivocatio
n, due to noise structure and not accounted by the CRB. The actual err
or is assessed by analysis and simulations.
