WebIn the military science of ballistics, circular error probable (CEP) (also circular error probability or circle of equal probability [1]) is an intuitive measure of a weapon system's precision. It is defined as the radius of a circle, centered about the mean, whose boundary is expected to include the landing points of 50% of the rounds. [2] Concept WebWhile 50% is a very common definition for CEP, the circle dimension can be defined for percentages. Approximate formulas are available to convert the distributions along the …
