Distributed Sensor Networks
Abstract
The Distributed Sensor Networks (DSN) Program is aimed at developing and extending target surveillance and tracking technology in systems that employ multiple spatially distributed sensors and processing resources. Such a system could be made up of sensors, data bases, and processors distributed through an area and interconnected by an appropriate digital data communication system. The detection, tracking, and classification of low-flying aircraft have been selected to develop and evaluate DSN concepts in the light of a specific system problem. A DSN test bed has been developed and is being used to test and demonstrate DSN techniques and technology. The overall concept calls for a mix of sensor types. The initial test-bed sensors are small arrays of microphones at each node augmented by TV sensors at some nodes. This Semiannual Technical Summary reports results for the period 1 April through 30 September 1985. Test- bed and tracking system improvements are described in Section II. These include the completion of a TV subsystem that has been added to the test bed, changes in tracking software to integrate and utilize the TV subsystem, the automation of test-bed interactions to improve usability, and the addition of floppy disks to test-bed nodes for data logging and for providing an additional data source for experiments. Section III described a series of real-time test-bed demonstrations that were performed during this reporting period. Section IV reports the results of three different acoustic tracking evaluation efforts. Keywords: acoustic arrays; digital radios.
