To enable end users to secure their territory against attacks from hostile missiles and aircraft, whether manned or unmanned, HENSOLDT has combined its TRML-4D air defence system (active radar) with its world-leading Twinvis passive radar to form the unique TwinSens solution.

Twinvis

Twinvis is a passive radar that uses existing electromagnetic signals from broadcast and TV transmitters and evaluates their echoes when reflected by an object. It remains invisible and therefore cannot be jammed or eliminated in a targeted action – a real advantage in the military field. More than 15 Twinvis units have already been sold.

TRML-4D

TRML-4D is a multi-functional C-band AESA radar for surveillance, target acquisition and weapon assignment. It provides a recognised air picture of the theatre. The radar is able to detect, track and classify various types of air targets, including cruise missiles, hovering helicopters and small, fast, low-flying and manoeuvring aircraft. More than 50 units from the 4D family have already been sold.

By combining two HENSOLDT systems, TwinSens offers unique functionalities and operational advantages. The exchange of sensor data between these two systems and common control enhances the performance of the overall solution compared to standalone sensors.

With TwinSens, customers get an air picture that is initially created without RF transmissions and consequently without the risk of GBAD systems being detected by enemy forces. This radar solution shows increased resistance to modern jammers and improves situational awareness, even for targets with an extremely small RCS.
