NESIS 4000
Naval electronically steered IFF systemThe challenge
Modern naval missions range from search and rescue to anti-piracy, border protection and full-scale combat scenarios. Whatever the situation, naval mission success and safety require situational awareness at all times.
Maritime assets have to conduct surveillance – especially to detect small, fast-moving targets, even in bad weather and low visibility – while seamlessly integrating data from multiple sources to help distinguish friendly from hostile forces and prevent fratricide.
With rough seas and the elements that can degrade conventional surveillance systems, ships also need robust IFF capabilities that provide stable and reliable imagery.
Furthermore, potential threats detected at greater distances can trigger early-warning systems, giving operators additional time to make informed decisions.
Our solution
The NESIS 4000 system features a fully 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.
Modern maritime defence require solutions that combine state-of-the-art imaging technology, rugged design and integration capabilities to distinguish friend from foe.
HENSOLDT’s NESIS 4000 is a next-generation, electronically steered, non-rotating IFF antenna system designed to prevent fratricide while overcoming the limitations of mechanically rotating antennas and providing real-time, lock-on track operation.
With real-time, high-resolution infrared and electro-optical imagery, operators can identify threats even from long distances using advanced sensors that increase the detection range for both air and sea threats.
Its 360° surveillance coverage and fully integrated mast concept provide optimised performance (including passive), installation and in-service support for multi-mode land and maritime operations.
Features and benefits
Features
- Line-of-sight range coverage of up to 200 NM
- Can control beam (interrogation) direction in any direction at any time and with the antenna turning faster – down to milliseconds
- Improved target-update times with the added option of locking onto targets independently
- Reduces the ship’s radar cross-section (RCS) through its design and avoidance of mechanical rotating parts
- Additional lock-on track mode permits LPI operation
- Fully passive operational mode based on
- ADS-B and Mode 5 Level 2 reception and tracking only
Benefits
- Adaptable thanks to modular design
- Fully active circular monopulse transmit/receive antenna array
- Zero compromise between range coverage and antenna turn time
- Electrical beam-steering technology significantly reduces maintenance issues and ISS costs due to reliance on moving parts
- Circular antenna design for a 360°- coverage, fully integrated mast concept with in-line installation with other sensor systems on the mast
-Interface between antenna and MSSR 2000 ID is reduced to a minimum of 3 RF and one fibre optic cable for control and monitoring
