Description

Multi-function surveillance and target acquisition radar

Step into the next dimension

TRS-4D is HENSOLDT Sensors' latest member of the C-Band (NATO G-Band) naval radar family. It is available with a single face rotating antenna and also as a four fixed-panel configuration.

Based on the most advanced Gallium Nitride ActiveElectronically Scanned Array (AESA) sensor technology with multiple digitally formed beams, the new generation TRS-4D opens a new dimension for maritime missions.

It is fully flexible, using an innovative and unique combination of electronic scanning technology and mechanical rotation.

This allows for unprecedented surveillance and unmatched threat detection and tracking performance to extend mission success and platform survivability. TRS-4D supports the countering of conventional and asymmetric threats.
