Reduction of False Alarm Rates in Peripheral Detection Systems.

Abstract

The distribution function of the time between false alarms which results from combining the output of two independent sensors in an AND-logic mode is derived. In particular, the false alarms from each sensor are assumed to be distributed according to Poisson laws (lambda 1 and lambda 2). A 'moving window' with a time interval tau is used such that an alarm for the combined system is triggered if, and only if, an alarm from each system occurs within an interval tau. Numerical results of using the derived distribution in combination with a simplified detection model are presented for a number of cases. (Author)
