Diehl Defence is enhancing its established Ground Based Air Defence (GBAD) System IRIS-T SLM by adding optional passive radar capabilities in order to increase the system's overall reconnaissance capacity.
Diehl Defence has selected HENSOLDT's Twinvis for this purpose. HENSOLDT will support the testing and integration of the passive radar components at Diehl's test and integration facility in Roethenbach, Germany.
The medium-range GBAD System IRIS-T SLM in its current configuration is equipped with the active multifunctional radar TRML-4D from HENSOLDT which is the main sensor of the IRIS-T SLM Fire Unit. Adding passive radar capabilities will provide IRIS-T SLM operators with the additional features of emission-free early detection of air objects as well as relaying the picture of an air situation to the operating personnel without radiating the main sensor.
The integration of passive radar functions optimizes the situational awareness of the Fire Unit on IRIS-T SLM, increases the survivability of the GBAD system by identifying, verifying and reducing the impact of hostile electronic counter measures and strengthens the assertiveness of Diehl's GBAD system against threats, both imminent as well as later on.
Integrating passive radar capabilities into IRIS-T SLM offers operators the supplementary option of a mobile and non-emitting radar solution for air target surveillance, which is complementary to the TRML-4D active radar. The additional feature can provide omnidirectional 3D tracking of more than 180 objects up to a range of 250 km (sensor-to-target).
