As a company that has built its reputation in the field of electro-optic and RF-based sensor solutions, HENSOLDT announced on April 2 the launch of NESIS 4000, a new IFF system for marine platforms, based on Active Electronically Scanned Array (AESA) technologies. This technology allows the system, which has a range of 200 nautical miles, to electronically form RF waves and to steer them toward targets without the need for the rotating antenna required by conventional radars.
According to HENSOLDT, the AESA technology removes the need for a rotating antenna at the highest point of a ship by using a non-rotating, ring-shape fixed-array antenna at a lower point on the ship’s integrated mast, which reduces significantly the radar cross-section and infrared signature of the vessel.
The first NESIS 4000 system will be delivered to its launching end user by the end of this year.
