This acoustic fingerprint is comprised of a material's spectral acoustic properties of impedance, sound velocity and absorption, which allow a computer to be programmed to automatically detect illicit materials such as plastic explosives.
The acoustic fingerprint is obtained by transmitting short, rapid bursts of wide bandwidth acoustic energy, receiving the returned acoustic signal, and processing the returned acoustic energy utilizing proprietary Acoustic Core(TM) spectral analysis tools.
