NESIS 4000
NESIS 4000 (Naval Electronically Steered IFF System) is operating in the L-Band (NATO- division: D-Band) secondary surveillance radar for naval vessels and land based platforms.
NESIS 4000 features an active transmit/receive circular monopulse antenna array that achieves line of sight range coverage of up to 200 NM, with zero compromise between range coverage and antenna turn time, and a reducing of the Radar Cross Section (RCS) of the ship. The direction of the beam (interrogation) can be controlled by the system in any direction at any time and with a faster antenna turning, down to milliseconds. The radar is compliant with AIMS; STANAG 4193 ED3; ICAO Annex 10 Vol IV.
