Searcher Speed for a Stationary Tight Crossover Barrier

Abstract

This technical note reports what appears to be a hitherto missing piece of barrier-patrol theory: the solution of the equation for a stationary (also known as symmetric ) tight crossover barrier. It has long been known, at least implicitly, that the equation in question is cubic in the ratio of searcher speed to target speed. The exact solution is derived here; it is algebraically complicated. The key result of this note is the identification of a remarkably simple approximate solution that is remarkably accurate for barriers wider than a few times the effective sweep width of the searcher s sensor.
