The Thales Vigile is a fourth generation electronic support measures (ESM) system tailored for naval applications (both surface and submarine).
The Vigile system provides wideband, high sensitivity reception (C to J bands) and pulse analysis with the ability to detect low probability of intercept (LPI) or invisible hostile radars using ultra sensitive search mode. The wide-open system architecture provides 360° coverage and 100% Probability of Intercept.
Furthermore, this ESM supports electronic intelligence (ELINT), precise de-interleaving, and specific emitter identification/platform identification using ESM tasked mode measuring signals frequency, phase and amplitude.
The system provides real, multiple, instantaneous radar acquisition and handling of up to 500 tracks. Also adaptable library generation by flexible programming and "on task" modification/updating capability to maximise the ability to cope with new tactical situations is provided.
When coupled with the Scorpion ECM system, this system provides a powerful EW suite capable of responding to any threat with very low latency.
The Vigile family consists of Vigile-400, Vigile-300, Vigile-200, Vigile-100 and Vigile-LW (Light Weight)
