STM delivered the upgraded version of the STM Through-the-Wall Radar (DAR) system to the Turkish Armed Forces following its use at civilian rescue operations.
The Turkish Armed Forces received a range of DAR supplies in accordance with the terms of the contract agreed by the SSB and the STM. The Turkish Armed Forces' numerous units will use the national technology DAR as an Under-Debris Live Detection Radar.

DAR was developed for Special Forces operations but found utility in live search efforts under the debris after the February 6 earthquake. It was later made available to civilians. DAR found more than 50 individuals under the rubble and saved their lives. The technology can detect the presence of a living human beneath the ruins based on chest and hand-arm movements when breathing, as well as micro-macro movements. DAR, which weighs around 6.5 kg, uses RF signals to instantaneously convey to the device whether there is a living being behind the wall/obstacle, as well as to determine the depth and position at which the living being is. The national system is designed to be utilised by a single person and may be set in the target area using tripods and similar instruments, as well as remotely controlled with a tablet computer. DAR's battery technology allows it to work continuously for more than four hours.
DAR has found a home in both military and civilian applications after being updated to reflect new areas of use.
STM Behind-The-Wall Radar
Through The Wall Radar (DAR) is a radar technology that uses ultra-wideband (UWB) waves to gather 2D position information of fixed and moving targets in enclosed locations without visual access.
Aside from military operations such as hostage rescue, counterterrorism, and homeland security, DAR can also be utilised for civilian purposes such as firefighting and disaster relief (earthquake, avalanche, fire).
DAR is also useful for migration and people smuggling.
