This report documents the results of an internal DRS effort to develop an Ethernet based integrated defense system to improve defense of cities, harbors, airports, power production, energy supplies, bridges, monuments, dams and so forth. Results of the integration of multiple SCOUT LPI radars and multiple Electro-optical targeting systems will be provided, illustrating the benefits of interfacing surveillance radars with imaging sensors to confirm detection and provide visual recognition and identification. An analysis of the handover errors will be provided including errors due to; sensor platforms location and orientation uncertainty, target location measurement errors, data latency and motion prediction errors, which contribute to target handoff and the re-acquisition timeline. These predictions will be compared to measured results. The system architecture will be defined including; security, support for both stationary and moving sensor platforms, remote control of sensor systems and distribution of imagery through the network and remote diagnostics, maintenance and software upgrades. Growth capabilities include secure wireless communication to/from moving platforms, integration with sonar and seismic sensors, cooperative location of friendly forces and acoustic detection and triangulation of gunshots with automated cueing of sensors and security forces to the shooters most probable location. The use of ad hoc multi-hopping wireless networking supplements hardwire networks, augments disaster response capabilities, provides high-speed communications for moving platforms and supplements GPS outage areas.
