Abstract

Using the probability density analysis mode in a digital correlator, a simple technique for determining the scattering distribution of large aerosols and the overall quantity of aerosols is developed. It is found that a simple measurement of the average count rate is sufficient for the assessment of the performance of both single-particle correlated laser Doppler and laser time-of-flight velocimeters. In terms of the experimental parameters and the measured quantity of aerosols, an equation that describes the power and range dependences of the unambiguous rate of remote wind speed measurements is derived. Laboratory experimental results that test the validity of this equation are reported.
