is the the median
miss distance; it is also known as the Circle of Equal Probability
. The CEP, expressed
as a distance
, defines a circle
about the aim point
. Half of the weapons dropped
at this point will strike inside this circle, and half outside. Their actual miss distances may vary wildly, making the average
miss distance much larger than the CEP.
This value is used by targeteers to determine roughly how many weapons are needed to achieve a desired Damage Expectancy (DE).
