HENSOLDT Introduces State-of-the-Art Radar

HENSOLDT, the independent sensor solutions house and provider of Air Defence and Weapon Locating Radar, COBRA (Counter Battery Radar), recently launched the multi-function air surveillance and target acquisition radar, TRML -4D.

The new radar is HENSOLDT’s latest member of the C-Band (NATO G-Band) ground based air defence radar family. Based on the Gallium Nitride Active Electronically Scanned Array (AESA) sensor technology with multiple digitally formed beams, TRML-4D is designed for near- to long-range ground-to-air detection and for weapon assignment. It is capable of detecting, tracking, and classifying various types of air targets, with a particular emphasis on small, fast, and low-flying and/or manoeuvring cruise missiles and aircrafts and hovering helicopters. The TRML-4D features a dedicated C-RAM and C-UAS mode.

Furthermore, its secondary radar is capable to deal with the interrogation modes up to Mk XIIA/S. TRML-4D’s unique concept of simultaneous multi-beams and Doppler processing ensures reliable performance of all operational tasks at a high update rate.

The radar is reportedly excellent in complex environments with mixed clutter and high target densities. TRML-4D can support most of the short range and medium range surface-to-air missile systems. It is designed for continuous operation and high operational availability.
The probability for zero critical failures during a 24/7 three-month mission of more than 99 per cent results in significant advantages on logistic support. Maintenance free missions are enabled by degradation using multiple solid state transmit and receive modules. The low MTTR, high reliability per component and the advanced built-in test equipment (BITE) together ease maintenance and facilitate the low life cycle costs of TRML-4D.

Fast and Accurate

Thanks to its electronic look forward/back scanning capability, the TRML-4D provides weapon systems with more time for reaction. For instance, it scans a dedicated sector twice per mechanical rotation (“cued search” function) depending on recon information. Also, it can initiate a track within a single scan (look back functionality) for threatening targets and automatically classifies specific targets as high priority threats and allocates additional radar illumination (“cued track” functionality).

Due to the higher track update rate resulting from this, the TRML-4D creates reliable tracks more quickly and with a minimum number of scans and, in this way, increases the time available to weapon systems for reaction, also in the case of manoeuvring and pop-up targets.

The precise calibration of all antenna parts in combination with the given antenna aperture in C band yields highly accurate tracks, even for the smallest of flying threats, in both symmetric and asymmetric conditions, to ensure exact and fast weapon assignment and increased hit probability.

Resilient and Reliable

Allocating radar resources to different scan types allows high-volume search and high-priority tracking to be combined in a sophisticated way. This combination of measurements ensures reliable tracking performance and target classification, especially for manoeuvring threats. Advanced, automatically triggered ECCM (Electronic Counter-Counter-Measures) and the tracker’s high saturation level guarantee the system’s performance even when jamming or interfering signals are present. The radar has sufficient capacity to uphold all functions simultaneously so as to ensure mission success even in stress situations involving a high density of targets.

Its modular architecture and its ability to be defined by software allow the radar system to be customised and its capability to be enhanced incrementally, so that it is up to date throughout its life and fit for future challenges at any time.

Completed with HENSOLDT Sensors’ well-established SSR (Secondary Surveillance Radar) interrogator MSSR 2000 I, TRML-4D provide the inevitable and reliable track identification to avoid friendly fire. The MSSR 2000 I is capable to deal with interrogation modes up to Mk XIIA/S, including Mode S and Mode 5.

Comprehensive Solutions

HENSOLDT is a pioneer of technology and innovation in the area of defence and security electronics. The company, headquartered in Taufkirchen near Munich, is a market leader in civilian and military sensor solutions, developing new products to counter a wide variety of threats based on disruptive concepts in such fields as big data, robotics and cyber security.

Military and civil radar systems have been part of the company’s core competences for decades. Today, HENSOLDT’s radar systems are in use around the world. In surveillance, reconnaissance, air defence and air traffic control, they provide their services in both military and civil areas.

Since 1955, HENSOLDT and its predecessor companies have been on the forefront of the development and production of radar systems. Significant R&D resources ensure the continuous development of radar solutions and technologies in the various domains to solve the challenges posed by a modern radar development. These are the solutions, which have enabled HENSOLDT to create numerous families of radar products since its inception.
