Abstract :
Derives the Cramer-Rao bound (CRB) for the frequency estimation from noisy signals of laser Doppler anemometer (LDA) measurement. The obtained result is different from the CRB for harmonic signals, which is widely used by most LDA engineers today. It is concluded that the CRB by the LDA burst is two to six times as large as that by harmonic signal
