An Extensible Solution for Distributing and Accessing Tactical Geospatial Information

Not Available The next generation of Navy shipborne radars must be designed to improve the detection low observable (LO) targets such as sea skimming missiles in littoral environments. These radars will be designed using solid state active array (SSAA) antenna technology. SSAAs utilizing space-time adaptive processing (STAP) can simultaneously reject land clutter, EMI and jam-ming, significantly enhancing the radar's ability to detect LO targets. The Phase 1 research that is being proposed by Technology Service Corporation (TSC) will in-vestigate the transition of STAP into both a notional S-band area defense and an X-band self-defense shipborne radar. The requirements for these radars will be specified, the best-suited STAP algorithms will be selected and optimized for shipborne applications, and the performance enhancements will be assessed. An adapt-on-transmit (i.e. Inverse STAP) concept will also be investigated. A transition task and a Phase 2 follow-on effort will select available software tools, perform de-tailed analyses of the STAP techniques and define experiments that can be performed using NSWCCD and other Navy facilities to validate the STAP algorithms' performance.
