Stationary / Mobile Ground Based Electronic Intelligence System - The SDD long-range system is designed for strategic reconnaissance, and monitoring naval and ground radar targets. The passive principle of operation gives SDD the ultimate concealment and security feature of „seeing without being seen“. The ELINT SDD system is designed to be a basic part of a technical intelligence system.

High sensitivity of the system allows reception of the signal reflected from the troposphere, thus ensuring working range beoynd radio horizon up to a distance of 700 km and 360°.

Perfect analysis of the received signal enables to get full information about the type and position of the targets. Searches, detects, analyses, identifies and locates 2D targets at sea and on land that emit electromagnetic signals within the frequency band of the SDD system.

System analyses, measures and displays signal parameters, compares them with sources database (targets database), identifies the sources (targets), and displays tracks on the digital map for slowly moving targets at sea or on land. It manages and monitors sources of electromagnetic signal under the area of coverage and provides information on the existing situation primarily to an Integration Centres and other ELINT, COMINT and weapon systems. System is able to be integrated with special integration centre for remote control of each SDD DF station.System have possibility to be integrated with TDOA system and display up to 200 real-time flying targets.

The system is first of all designed for reconnaissance of a wide range of naval and ground RF sources within an extensive reconnaissance area (up to 700 km and 360°).
  • Automatic detection of incoming signal direction and its technical parameters
  • Processed signals:
  • continuous or pulse; amplitude, frequency and phase modulation including their combinations
  • Displaying of radioelectronic situation using interactive graphic processing (maps, tables, measured data)
  • Automatic testing of basic functions during the operation
