Abstract
Earlier analysis of the use of laser-beam scintillations to measure path-averaged rainfall rate and drop-size distribution has been well verified for pathlengths up to 140 m even though, for such a path, overlapping of the scintillation patterns violates a simplifying assumption of the analyses. Analytic extension of the theory to the case where the scintillation patterns overlap appears intractable, so a computer simulation has been used to investigate that limitation of the theory. That simulation, presented here, verifies that the original scintillation–covariance technique for measuring rainfall parameters is, with only a slight modification, still applicable in the presence of overlapping scintillation patterns from many raindrops.
