Use of Circular Error Probability in Target Detection

Abstract

This paper describes an algorithm for calculating Circular Error Probability (CEP), which is frequently used with target location estimates. CEP relates measurement errors to the variation of a calculation that is computed from those measurements. A mathematical foundation is provided for the CEP estimate and the algorithm is shown to be extremely accurate. It differs from the true CEP estimate by less than one percent on average and has a maximum error of 1.5 percent. As such, it is a useful tool for assessing both the accuracy and sensitivity of any calculated quantity to errored input. (rh)
