Wideband Array Processing For Acoustic Detection and Tracking Of Aircraft/sup */

The Distributed Sensor Network Program, sponsored by DAFPA, has as its goal the development of technology to enable the construction of defensive systems of geographically separated sensors and distributed computational resources. In general such a system would consist of autonomous nodes that would work cooperatively to detect and track targets of interest and would report interesthg situations to a user (or set of users) through some interface. Each node would consist of appropriate sensors and processors (hardware and software) to permit it to perform some tasks independently of other nodes and communications to permit it t o work cooperatively with other nodes to form a viable distributed system.
