Hensoldt has developed NESIS 4000, a next generation naval identification-friend-or-foe system that allows for improved performance and ship survivability, the company announced on 2 April.
NESIS 4000 is based on active electronically scanning array (AESA) radar technology that allows the radar beam to be steered electronically, eliminating the requirement of a mechanically rotating antenna on top of the ship’s mast. Instead, the use of a non-rotating, ring-shape fixed-array antenna in a lower part of the ship’s integrated mast significantly reduces the radar cross-section and infrared signature of the vessel.
The AESA technology also increases radar performance. Compared to conventional systems, targets and eventual threats can be identified much more quickly, and the 360° detection range is widened to a 200 NM radius.
The first system will be delivered to the launch customer by end of 2019.
