Design of an Acoustic Target Intrusion Detection System Based on Small-Aperture Microphone Array

Automated surveillance of remote locations in a wireless sensor network is dominated by the detection algorithm because actual intrusions in such locations are a rare event. Therefore, a detection method with low power consumption is crucial for persistent surveillance to ensure longevity of the sen...
