Electronic Warfare (EW) is of prime significance in modern warfare, both for short-term reconnaissance and long-term purposes. Electronic Support Measures (ESM) system is the most important EW component required for ground (shore-based), surface and airborne applications, especially in maritime scenario. RIBAT-2S cover all the essential features available in ESM systems being used by modern navies worldwide. The system is able to detect, classify and track both CW and pulsed radar emitters operating in 0.5 - 18 GHz frequency band. RIBAT-2S has 100% POI, high sensitivity, and instantaneous frequency measurement with high accuracy, fast reaction time and threat identification. The system is compact, lightweight, and can easily be interfaced with other onboard sensors and systems.
