A pulsed laser radar designed for satellite and lunar ranging must respond to weak light signals received from great distances. This paper deals with the effect of photoelectron fluctuations on the ranging accuracy of such a laser radar using a photomultiplier for a detector. The authors, assuming threshold detection, introduce an equation of standard deviation for errors in measured ranges which occur when the photomultiplier output fluctuation is expressed as a Poisson distribution. The accuracy of satellite observation data obtained at the Dodaira Station of the Tokyo Astronomical Observatory was about 2 meters, which was shown to be close to the limit accuracy where our system parameters are used.
