All-Signal Tactical Real-Time Analyzer (ASTRAL)
Abstract
The All-Signal Tactical Real-time Analyzer (ASTRAL) program developed and demonstrated a system for radio frequency and optical electromagnetic signal surveillance and environment understanding. Built on technologies explored under the Dynamically Composed RF Systems program, also budgeted in this PE/Project, the objective of ASTRAL was to provide a factor of at least 1,000 times improvement over current signal awareness processing speed over broad spectral coverage. The program used technology that supports a development path leading to a mobile, tactical capability. The development objectives of the ASTRAL program were to (1) develop a hybrid processor that provides real-time processing of the most challenging Low-Probability-of-Intercept (LPI) threat signals across a wide bandwidth, and (2) identify exploitation algorithms for military applications that are well-suited to this type of hybrid processor. Several strategic and tactical spectrum awareness applications that were addressed include, but are not limited to: (a) real-time exploitation of optical communications, (b) city-wide wireless device geo-location, (c) broadband LPI radar warning, and (d) theater-wide spread-spectrum LPI radio geo-location. ASTRAL transitioned to the Navy.
