Abstract

The present invention uses a pair of phased array of microphone panels in conjunction with a digital signal processor, disk storage, and beam-steering and noise suppression algorithms to discreetly provide a phased array surveillance system (PASS) for audio data. The above elements are covertly housed in a briefcase, for instance. Also included is a wireless RF transceiver system that relays data picked up by the microphone array panels to a remote unit for real-time analysis. The remote unit is also capable of controlling the beam forming and noise suppression algorithms as well as perform beam-steering of the PASS unit allowing the remote operator to selectively target individual speakers in real-time. Data recorded by the PASS unit is made available for subsequent analysis using beam forming and noise suppression algorithms.
