摘要：The primary goal of the project is to prove that passive location fixing is feasible over a distributed wireless network which can form basis for 'low cost' solution for security applications where any acoustic activity can be detected by multiple transducers deployed along the area of interest. The microphone grid serves as a multi-transducer network to detect sound disturbance in the area of interest. The outputs from the various transducers are sent to a central processing unit which post processing sends accurate location of the source. The presented work encompasses the design and implementation of the generic platform hardware (nodes), a simple but effective way to achieve time synchronized acoustic data from various nodes connected over RF transceivers and to achieve passive localization by visual representation of multi transducer nodal information
