Multi-Functional Air Surveillance and Target Acquisition Radar System


  • Active electronically scanned array (AESA)
  • IFF: Integrated antenna, IFF system functionality
  • Digital Beam Forming (DBF)
  • Pulse Doppler processing in all beams
  • Sophisticated classification algorithms
  • Electronic counter-counter measures (ECCM)
  • Areas of interest (Cued Search)
  • High priority target tracking  (Cued Track)


The TRS-4D/TRML-4D Radar Family encompasses HENSOLDT’s latest members of C-Band (NATO G-Band) state-of-the-art naval and ground tactical radars.

The members of the TRS-4D/TRML-4D Radar Family provide multi-functional surveillance and target acquisition offering recognized tactical pictures and weapon assignment.

Based on the most advanced solid state 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 maneuvering cruise missiles and aircrafts and hovering helicopters.


  • Instrumented range: 250 km
  • Azimuth coverage: 360° (rotating), 100° (fixed)
  • Target detection capability of 0.01 m² RCS
  • Capacity of 1500 targets 3D tracking
  • Track range performance: fighter aircraft  > 120 km , supersonic missile > 60 km
  • Track update rate: < 1 s
  • MTTR: < 0.5 hrs
  • Highly mobile, set-up and de-camp within 10 minutes

Main Benefits

  • Unique concept of simultaneous multi-beams and Doppler processing ensures reliable performance of all operational tasks at a high update rate.
  • Excellent performance even in complex clutter environments and high target densities.
  • Support of short range and medium range surface-to-air missile systems.
  • Designed for continuous operation and high operational availability. Maintenance free missions are enabled by graceful degradation through the use of 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.
