CEP is an acronym for Circular Error Probable which refers to the radius of a circle within which half of a projectile's impacts are expected to fall. There are several synonyms for the term CEP such as the impact radius, the dispersion circle, and the shot distribution circle. Other terms used to refer to the same concept include the probable error radius or the 50% hit probability radius. In military parlance, the term "diameter" is often used as a synonym for CEP as it connotes a similar notion of the possible area of impact of a projectile.
