From Naval Hensoldt TRS-4D Radar to PrecISR Airborne

Hensoldt, NATO’s main supplier of sensors, is involved in major projects around the world. Its solutions are used in the F-16, Gripen, Rafale and Eurofighter aircraft, the TanDEM-X and EDRS-A satellites and the A400M transport aircraft. different models of helicopters; Critical mission teams for armored vehicles from Puma and Leopard, class 212 and 209 submarines, LCS Freedom ships of the US Navy and K130 corvettes of the German Navy.

The world’s most important armed forces use our sensors, radars, periscopes and electronic warfare systems, explains Luis Gueren, Marketing Manager for Latin America. Critical Infrastructure Protection, Air Defense, Aircraft Self-Defense, Signaling Information and Data Connections, Thermal Imaging and Optron Segmentation are the goal of solutions from a company founded three years ago when Airbus sold 75% of its business from Defense Electronics to Global Investment company KKR.

In 2018, Hensoldt bought the remaining shares and has since approached global markets as a completely independent company. This independence has allowed us to open 5 centers around the world, provide ad hoc solutions and create new solutions, which has opened up new possibilities for us, says Gueren. Another big step was taken in 2020 with the IPO: the largest IPO in Germany in 2020.

TRS-4D and SharpEye radars

Hensoldt offers a large number of marine radars such as the TRS-4D and the Sharpeye; terrestrial like the TRML-4D, the passive Twinvis and the ARS-NG; and also Areos like the PrecISR for ISTAR missions. In addition to primary radars, there are secondary radars such as IFF identification and systems for friends and foes. With 5 decades of experience in the design, manufacture, integration and maintenance, including military cryptographic computers, Hensoldt is currently one of the leading providers of IFF (Identification Friend-or-Foe) Mode 5 technology and capability worldwide.

The IFF portfolio is also certified with AIMS and NATO STANAG 4193 Ed.3, which guarantees full interoperability between US allies and NATO. The TRS-4D radar has been chosen by navies around the world: countries in the Middle East, the United States, Germany, and Latin America. With advanced technology for advanced missions, it provides unparalleled surveillance for Air Defense (AAW) and Surface Combat (ASuW) and is also suitable for anti-piracy, humanitarian aid, and search and rescue (SAR) missions.

Hensoldt delivered the TRS-4D to the 4 F125-class frigates of the German Navy, which installed a fixed, non-rotating plate. I also selected them for the second batch of 5 corvettes (in the past the K130s already had the Hensoldt TRS-3D radar). This year the Bundestag selected the TRS-4D for its MKS180 frigates. Also the US Navy. chose him for his Freedom Class LCS (Littoral Combat Ship) program. As in Germany, the first US Navy units used TRS-3D.

The delivery of TRS-4D radars to both navies confirms the success it has achieved in Europe and the United States. However, it’s also important to keep in mind that the Chilean Navy in Latin America has chosen the TRS-4D rotary version as part of a modernization program for its 3 Type 23 frigates. On the other hand, the takeover of the English company Kelvin Hughes (today you can complement your sensor portfolio with Hensoldt UK).

The SharpEye radars set the international standard in solid-state radar sensor technology. Used by civil organizations and defense agencies, they provide high performance, tactical and situational awareness supported by innovative radar visualization software. It offers unmatched coverage and is capable of capturing the smallest of targets on land, at sea and at greater distances than traditional magnetron-based radars.

Today more than 30 marine and coast guards worldwide benefit from this comprehensive and innovative solution. In the UK, for example, SharpEye systems are used by Royal Navy Type 23 frigates, Hunt and Sandown class mine countermeasures, RFA support and fast patrol boats, and Astute, Trafalgar and Vanguard class submarines.

Luis Gueren explains: Here in Latin America, Brazil and Colombia use our radars. In the second half of 2019, 4 new Kelvin Hughes SBS-900 coastal surveillance radars were integrated into the fixed coastal surveillance system operated by the Colombian Navy. This family contains the SharpEye digital transceiver and is configured to provide an environmentally friendly, pole-mounted assembly.

The system is designed to provide integrators with a complete radar sensor that meets the requirements of a coastal surveillance system or radar that is part of a VTS (Vessel Traffic Service) system. With an innovative carbon fiber housing and a gyro unit, the SharpEye has redefined the method for using marine radar antennas and transceivers. A direct drive motor eliminates the need for a gearbox, which significantly reduces installation and maintenance costs while providing unmatched reliability.

PrecISR, find a needle in a haystack

Hensoldt has a portfolio of airborne sensors and systems for intelligence, surveillance and reconnaissance missions that can be supplied individually for small aircraft or more complex ISR (Intelligence, Surveillance and Reconnaissance) sets for medium-sized aircraft such as the C295. The PrecISR radar converts the latest advances in active matrix technology and the AESA (Active Electronic Scanning Array) digital receiver into a scalable, high-performance sensor that can be installed on board helicopters, unmanned aerial vehicles and fixed-mission aircraft.

Due to the software-defined radar modes and the direction of the electron beam, the PrecISR can perform various tasks almost simultaneously. It is capable of detecting, tracking and classifying more than a thousand objects, literally finding a needle in a haystack. Thanks to its compact design, it weighs only 55 kg. The fact that all radar-related components are located outside the fuselage greatly simplifies the integration of the air platform into the PrecISR.

It is designed for all types of air surveillance missions operating 24 hours a day, 7 days a week, in all weather conditions. The PrecISR 1000’s ground surveillance capabilities include the detection and characterization of fixed targets using the Moving Target Indicator (MTI) and Synthetic Aperture Radar (SAR) in spot or strip mode. For maritime surveillance, characterize marine targets by operating the ISAR (Synthetic Reverse Aperture Radar) and range profile.

The aerial surveillance functions include detecting and intercepting aircraft flying at low altitude, collecting direction and speed information from all types of targets for their correlation with data from other sensors. According to Pierre Marquis, PrecISR Sales Director, the proven, powerful and compact design of the radar enables surveillance missions of large areas in a single passport and enables full 360-degree coverage, regardless of the flight orientation of the radar, an unmatched level of situational awareness with significant savings the flight costs.

The Lyncea Defend command and control system

Lyncea Defend was created to protect ships from typical asymmetric threats in the air, sea and land. With it, Nexeya France (a subsidiary of Hensoldt) has developed an integrated 360-domain command and control system for self-defense (C2), which includes a series of integrated sensors to detect and protect against threats from above, below and above the ground. Water surface and land. The Lyncea Defend Command and Control (C2) system was developed with the aim of assisting the ship’s crew with a comprehensive tactical assessment of the situation.

The centralization of data speeds up the decision-making process, supports the analysis of critical threats and enables you to quickly assign suitable countermeasures. Potential threats are tracked and classified according to their degree of threat using intelligent decision-making aids. Automatic visual and audible alarms notify operators of threats. The appropriate countermeasures can be assigned manually by the crew or automatically by the system. The Lyncea surveillance UAV is used for damage assessment.

The remote navigation radar, aerial UAV radar, high frequency scanning detector, diver detection sonar, laser warning device, optical day and night cameras, and Lyncea surveillance UAV are used to detect threats. Countermeasures include laser glare, a UAV jammer, underwater megaphones, and Lyncea’s weapon system. The A69 and POM offshore patrol ships are already in service on the French Navy’s flower monitoring frigate. It is also used on ships of the Cameroon and Senegalese navies. (Juan A. Arteaga)
