Abstract

Commercially available digital signal processors (DSPs) can be used to host state-of-the-art air acoustic adaptive beamforming algorithms in low power, low cost, real-time sensor systems. These systems are suitable for use as both unattended ground sensor and in vehicle mounted microphone array applications. This paper describes a compact state-of- the-art, real-time adaptive beamforming approach and sensor hardware for vehicle mounted array operation. Recent field test results are presented for detection, tracking, and classification results with the vehicle engine idling as well as with the vehicle 'on the move.' Tracking accuracy results are also presented. The system tested used an eight- microphone array on the SARGE with two additional microphones located near the engine and the exhaust for additional adaptive noise cancellation.
