Paper Abstract
Detection, classification, and localization of potential security breaches in extremely high-noise environments are
important for perimeter protection and threat detection both for homeland security and for military force protection.
Physical Optics Corporation has developed a threat detection system to separate acoustic signatures from unknown,
mixed sources embedded in extremely high-noise environments where signal-to-noise ratios (SNRs) are very low.
Associated neural network structures based on independent component analysis are designed to detect/separate new
acoustic sources and to provide reliability information. The structures are tested through computer simulations for each
critical component, including a spontaneous detection algorithm for potential threat detection without a predefined
knowledge base, a fast target separation algorithm, and nonparametric methodology for quantified confidence measure.
The results show that the method discussed can separate hidden acoustic sources of SNR in 5 dB noisy environments
with an accuracy of 80%.
