Abstract :
We consider a digital signal processing sensor array system based on randomly distributed sensor nodes for intrusion and surveillance applications. The nodes having acoustical, seismic, and other sensors are self organized into a synchronized network using low powered spread spectrum transceivers. Beamforming array techniques for enhanced detection and estimation and performances under various ideal and practical conditions are presented
