XAREA--A FORTRAN Subroutine to Find the Intersection Area of an Annulus with a Circle

Abstract

When aircraft are flushing from a base under attack, the portion of the force that will escape to carry out the mission must be known to a relatively high level of confidence. This involves the determination of the probability of kill associated with the base force. One major component of this term is the geometrical intersection of the weapon's effective kill volume with the region containing all aircraft at any instant in time. Subroutine XAREA calculates a numerical value for this intersection in terms of area. (Modified author abstract)
