An analytic barrier surveillance model for fixed and mobile platforms / by B. A. Trenholm. : D68-16/7-1994E-PDF

"This report documents the barrier surveillance model used in DMOR Project 21279-12 "Atlantic/Pacific Undersea and Surface Surveillance Options". In this model surveillance is limited to the initial detection and cueing function. When very large areas are involved a less costly cueing solution is to provide one or more layered barriers rather than full area coverage. The classic Koopman random research model is adapted to the problem of barrier surveillance and applied to fixed systems as well as mobile search systems. Barrier surveillance is modelled as area search subject to a time constraint which depends on the minimum time for a target to transit the barrier. A special variant of the model is developed to meet the unique requirements of maritime patrol aircraft. The depth of a barrier depends on the capability of the surveillance systems. For some of the systems considered, the barriers may be sufficiently wide that significant area coverage is achieved"--Abstract, page ii.
