ABSTRACT:
A system for generating a threat alert in an infrastructure component is provided. The system includes multiple acoustic sensors configured to detect a signal. The system also includes a processing circuitry including at least one analog-to-digital converter configured to digitize the signal. The processing circuitry also includes a digital signal processor configured to process the acoustic signal in a sequential routine. The sequential routine includes a noise filtering routine configured to filter background noise from the acoustic signal and generate a filtered signal. The sequential routine also includes a source identification routine configured to identify a source generating the acoustic signal based upon the filtered signal. The sequential routine further includes a threat analysis routine configured to detect a threat based upon the source identified and generate a threat level signal.
