Pass rate analysis of interception heuristic against border crossers along a linear border

In this paper, interception of border crossers along a border strip bounded by a border line and a military boundary line is considered. Performance measure of interception strategy of a guard is mission failure rate: pass rate of border crossers through the border strip. A defenceable area and a lateral defense length of sequential two-target interception are introduced to derive an expression of an upper bound of pass rate. Numerical simulations of border defense validate the upper bound.
