Sheldon J. A closed form expression for line-of-sight probability

Army Materiel Systems Analysis Activity Aberdeen Proving Ground, MD, 1977. — 34 p.This report examines expressions for line-of-sight probability as a function of observer altitude H and observer target range R. The result for a somewhat rough terrain classification is P sub LOS = 1 exp -(97.59267)H to the power 0.689606/R and the result for a smooth table-top terrain classification is sub P sub LOS = 1 exp -(770.748)H to the power 0.6092/R.
