NESIS 4000

The NESIS 4000 (Naval Electronically Steered IFF System) is a secondary surveillance radar operating in the L-band (NATO D-band) designed for naval vessels and land-based platforms. It incorporates an active transmit/receive circular monopulse antenna array, providing line-of-sight range coverage up to 200 nautical miles without compromising antenna turn time. This system allows for rapid, millisecond-level control over the interrogation beam's direction and contributes to a reduced radar cross-section for the host ship. The NESIS 4000 is compliant with AIMS, STANAG 4193 ED3, and ICAO Annex 10 Vol IV standards.
