Electronic support measure gathers intelligence through “intercepting” electromagnetic radiations of military interest. Electronic support measures can provide:
1. Initial detection or knowledge of foreign systems
2. A library of technical and operational data on foreign systems
3. Tactical combat information utilizing that library

  • Capable of intercepting different types of transmitter signals such as:
    • Conventional pulse radar signals
    • CW radar signals
    • Frequency agile radar signals
    • PRF staggered radar signals
    • PRF jittered radar signals
    • Pulse-Doppler radar signals
  • Ability of eliminating one or more section (direction) of space by eliminating one or more of  directional antennas
  • Working in high density of signals environment
  • B.I.T.E facility
  • Link to GIS software
  • Link to data base or data bank
  • Link to position finding software
  • Connect to GPS or compass


ESM system is an advanced passive tactical receiving system for the radar signal, which can be used in different platforms like airborne, shipboard and submarines as well as ground based applications


Other System Features

4.1. System Control
This operator can control the operation of the system using trackball or keyboard whichever he prefers or is comfortable to work with.
4.2. Alarm State
The system has two modes “silent” and “alarm”. If the alarm mode is selected, when CW signal or threat locks on the system platform, the alarm will be activated.
4.3. Angle Display
The angle display can be performed in two selectable modes “relative” and “true” bearing. When relative mode is selected the angle will be displayed with respect to the heading of the platform. When the system is installed in moving platforms (such as aircraft or ship), the heading of the platform with respect to the north might be changing continuously. Selecting the true bearing mode, uses the platform navigation information to display the angle with respect to actual north direction. This feature requires compatibility of platform navigation information with ESM and should be checked with the existing facilities available on the platform.
