Before a mission, ELSIM generates RF signals to validate electronic warfare and radar systems. Powered by the Avantix Caracal database, ELSIM generates realistic signals to control the quality of mission sensors.

Integrated within a shelter, ELSIM actively responds to signals from various platforms (air, land, sea). ELSIM enables the emission of radar signals from antennas for testing, as well as aerial and naval validation for tactical simulations. In addition, ELSIM enables test benches for pre-mission validation and laboratory testing of entire EW systems with unplugged signal emission.
