Excalibur
Advanced Capability in a Modular 3U VPX Architecture
Excalibur is SNC’s next-generation, high-performance electronic support measures (ESM) and electronic intelligence (ELINT) sensor, delivering total radio frequency (RF) situational awareness across the 2–18 GHz radar spectrum. The system is designed to enable operators to detect, identify, geolocate and stream radar signals in real time for missions requiring extreme sensitivity, high probability of intercept (HPOI) and precision direction finding. Built on SNC’s proven family of ESM systems, Excalibur brings advanced capability in a compact, modern and modular 3U VPX architecture.
