Elt Roma is a part of Elettronica Group

The ELT/800 is ESM/ELINT equipment designed for Patrol/ISR aircrafts, based on a dual receiver architecture (wide open and wide band SH Digital Receiver) through a new system approach and modern technologies. The system performs both Tactical Surveillance (ESM function) with Warning and Self Protection capability combined with highly accurate data analysis for Intelligence (Technical ELINT function).


  • Very High Interception Probability
  • Wideband radio frequency coverage (C to K bands)
  • Automatic warning of high priority emitters
  • Dedicated functions for data collection, recording and accurate processing (Interpulse and Intrapulse analysis / MOP Analysis)
  • Fast and unambiguous threat identification exploiting all of the measured emission parameters (e.g.: FREQ, PW, PRI, TOA, ARP, MOP)
  • Capability to operate also with raw data libraries (mission data)
  • Automatic analysis, classification, display and recording of even unknown emissions
  • Capability of coping with high density environments in presence of all types of emissions both in warfare and law enforcement scenarios
  • Accurate Intra-pulse and Inter-pulse characteristic measurements through Digital Receiver for Fingerprinting purposes
  • Instantaneous Fine Direction Finding measurement through TDOA techniques and advanced geo-location capability of slow moving targets based on the twin channel Digital Receiver
  • Extensive recording capability for intelligence analysis
  • High reliability and maintainability
  • Reduced packaging and weight to meet even the most demanding installation constraints
  • Flight line re-programmable
  • Easy field maintainability (LRU philosophy).

All versions can be interfaced with multi-function displays and integrated with ECM systems and platform data bus.
