A major part of our Surface Surveillance Program involves using advanced signal processing and adaptive-array techniques for locating communications emitters in high-interference environments. We’re also investigating how advanced processing techniques can maintain surveillance radar performance in hostile electronic environments. A second major emphasis is on Tactical Air Defense which includes a broad range of activities in the detection, location, identification, and engagement of air vehicles. We combine the modeling results of phenomenological investigations and testing insights from air vehicle measurements into system performance predictions. Our suite of state-of-the-art instrumentation sensors includes two business-sized jet aircraft with instrumented radar and infrared sensors and electronic countermeasure systems.
