HENSOLDT’s Advanced Radar Technologies Countering New Threats in the Maritime Domain

Naval Forces are facing numerous new threats in today’s maritime battlespace which require unprecedented sensor capabilities. Both blue water missions and littoral scenarios are characterized by a high threat density which, together with adverse environmental conditions, pose real challenges to the ships’ mission effectiveness and survivability. New radar technologies, smartly employed by HENSOLDT’s latest TRS-4D naval radar, offer an effective, versatile and affordable answer to these multiple new threats.

TRS-4D marks HENSOLDT´s innovative step beyond conventional radar systems into a “new dimension” of operational capabilities. Based on the latest Gallium Nitride Active Electronically Scanning Array (GaN AESA) antenna technology, smart and dedicated exploitation of AESA scanning in azimuth and elevation enables high search efficiency, track initiation performance, accuracy and track stability. The TRS-4D radars have been successfully introduced into service with demanding European and U.S. customers (for example, the non-rotating variant on the German F125 frigates and the rotating variant on the U.S. Navy´s LCS-class ships). The TRS-4D provides a proven, low risk, modern solution that is interoperable with other partners, allowing for reliable obsolescence management for long periods.


TRS-4D Naval Radar

An attractive and promising ITB/VP (Industrial and Technological Benefits/Value Proposition) concept allows local industry to develop production capabilities, increase know-how, participate in feature growth and project work packages. HENSOLDT’s long-term experience in developing and fulfilling attractive ITB/VP concepts creates opportunities for long-term and sustainable development of capabilities, capacity and international competitiveness as well as growth potential for local companies.

TRS-4D has shown excellent performance on land, in blue water and in complex littoral environments with mixed clutter and highest target densities. It is capable of detecting, tracking and classifying various types of air and sea targets, with particular emphasis on small, fast and low-flying missiles, small agile surface targets, fixed-wing aircraft and hovering helicopters.

Combined with sophisticated dynamic resource management, the AESA capabilities increase track update rates as well as accuracy required to counter current threats. Modern digital technology and compact design allow for easy integration with the long list of sensor equipment in a modern warship. Cued Track enables the robust tracking of identified high priority targets (either automatically or by external designation for enhanced target tracking support).


TRS-4D during Sea Trials

Operation of the radar system is optimized for minimum operator workload and automatically adapts to the environment. For instance, traffic maps are included and prevent false alarms from vehicle targets near the coastline.

The radar system is designed for continuous operation and high operational availability with a high Mean Time Between Critical Failures. Maintenance-free missions are enabled by Military Off-The-Shelf (MOTS) high quality components and an architecture that allows for graceful degradation through the use of multiple solid state transmit and receive modules. The low Mean Time To Repair (MTTR), high Mean Time Between Failures (MTBF) per component and the advanced built-in test equipment together assure easy maintenance and enable low Life Cycle costs of the radar system.

The innovative digital beam forming design of the TRS-4D combines multiple simultaneous beams on receive in elevation for fast volume search and electronic agility in azimuth.

The all-in-one mode of the non-rotating system provides automatic detection and tracking of air and surface targets with an optimized waveform exploiting the possibility to scan electronically any direction within the hemisphere. By comparison, the rotating variant fully exploits the AESA features under the constraint of the mechanical rotation: look-forward and look-back features enhance the cued track functionality tremendously. First, the tracks for dedicated targets are more stable, tracks for defined threats are more quickly set up and knowledge from other sources (neighboring radars, satellites, etc.) are detected more quickly. TRS-4D is designed to provide a reliable tracking for a wide variety of targets at a very low false alarm rate.
