Design and implementation of a fiber optic perimeter intrusion detection system

This paper explains the design of a real time fiber optic intrusion sensing system. The said system operates passively on the field, unlike most of its counterparts, without any performance compromise. Optical signal processing and electronics is discussed. Simulation results are included in order to support the design. Signal estimation is accomplished through novel stochastic estimation technique. The POD of the system is found to be greater than 90% through extensive testing.
