An Aural Detection Model

Abstract

The report describes an aural detection model for detection of low flying aircraft. It incorporates ambient sound pressure levels, weather conditions (including wind effects), and attenuations of the signal along the flight path, and allows target signatures to be inputed as measured at aspect angles. The output of the model includes a probability of detection versus time together with all pertinent conditions at time of detection.
