Abstract : A methodology for an analytical derivation of visibility probabilities of n stationary target points in the plane is developed for the case when shadows are cast by a Poisson random field of obscuring elements. In addition formulate for the moments of a measure of the total proportional visibility along a star-shaped curve are given. The general methodology is illustrated by some examples of visibility along the circumference of half a circle, when the obscuring elements are centered within a concentric annular region. The distribution of the measure of proportional visibility is approximated by a mixed-beta distribution. (Author)
