Turkey’s state-owned Anadolu Agency reports that the Turkish Undersecretariat of Defence Industries (SSM) has formally accepted the Meteksan Savunma MİLDAR millimetric wave (mmW) radar for use on the Turkish Aerospace Industries (TAI) T129 ATAK attack helicopter.

The SSM commissioned Meteksan to develop the MİLDAR in 2013. In December 2016, Meteksan and TAI began testing the MİLDAR from onboard the T129 ATAK. Meteksan aimed to see serial production of the MİLDAR commence in 2018 or 2019.

A mmW radar is an extremely high frequency (EHF) radar capable of transmitting radio waves from 30 to 300 GHz. Lower power requirements enable for relatively compact and lightweight radar suites, suitable for lightweight aircraft. The MİLDAR, like other mmW radars, can augment electro-optical and infrared (EO/IR) sensors in searching, identifying and engaging targets on land.

Notes & Comments:
The MİLDAR aims to provide the T129 ATAK with analogous tracking and engagement capabilities to the AN/APG-78-equipped AN-64D/E Apache Longbow/Guardian. However, one of the marquee elements of the AN/APG-78 is its integration to the AGM-114L Longbow Hellfire anti-tank guided missile (ATGM). The Longbow Hellfire uses a mmW seeker that works with the AN/APG-78 to engage targets.

Roketsan would have to transition the UMTAS ATGM-series, which currently semi-active laser-homing or imaging infrared (IIR), to a mmW seeker to achieve a similar solution. An alternate route could be to data-link the MİLDAR to the UMTAS wherein the UMTAS receives location data from the MİLDAR until it is close enough to the target to switch to the terminal-stage IIR seeker.

Ideally, the MİLDAR would also be positioned from the T129’s top-rotor, as opposed to occupying wing or hardpoint stations on the side. Granted, several T129s could operate together, with one serving as a scout or radar-unit for the flight. However, in 2016 Meteksan stated (text in Turkish) that efforts were underway to ultimately configure the MİLDAR above the top-rotor.

Meteksan Mildar Milimetric Wave Radar


Shooting Control Radar (AKR) is a radar that operates at millimeter wave frequencies, providing shot control capability and navigation assistance for off-road helicopters. It can detect and follow targets in bad weather conditions day or night, and can show obstacles in front of the platform by providing height information. AKR has low power, weight and dimensions as well as low probability of catching.

AKR has two functions:

Shooting Control Function
AKR detects moving targets quickly and is starting to follow. AKR, pilota offers pilots on the radar screen for possible targets that create 360 ​​degrees state awareness. At the same time, the helicopter increases attack and rescue abilities by allowing multiple targets to be engaged.


Terrain Profile Creation Function
It is important to determine the altitude and obstacles in the navigational platform of the helicopter platform in terms of navigation safety. With this function, the radar pilot will scan the direction and angle range desired and present the terrain profile in real time with Pilota. The profile produced is updated periodically to prevent any losses that can occur especially on low flights.

Helicopter Attack Power 4th Floor, Defense Power Increased 7 times with Mildar Fire Control Radar to be Integrated with Weapon Systems. Mildar will be able to provide Land Elevation Information in addition to the Multi-Target Tracking Function in order to support Pilot Navigation in the difficult terrain conditions where the Terrain Profiling Function and the View Distance. Radar Under the Conditions Where Electro-Optic Systems Are Inadequate A large area can detect and track targets by fast and efficient automatic searching and transfer target information to weapon systems, even in difficult weather conditions.

Automatic Landing and Departure System Radar OKIS is being developed as a sensor system to be used in the safe landing and take-off of unmanned aerial vehicles. Designed as a single impact radar, the OKIS will provide precise position information to the automatic takeoff landing system. The system can be used in ANHA as well as other national HRA.

The RESTORE will have SAR (Artificial Spatial Radar) in addition to the target detection and tracking function. The radar system, which will provide detailed analysis of the user's standing targets with the SAR (Artificial Spatial Radar) mode, will also prevent the aircraft from impacting the terrain obstacle along the flight directions thanks to the land profile extraction feature. The radar system's mode of land profile creation and detection and tracking modes of air and land vehicles can operate at the same time.

BOTH RAIL will be used in unmanned aerial vehicles with low utility load capacity. The system can also be used as a fire control radar in armed RPEs.

The related prototypes to be developed within the scope of the project are mounted on T129 helicopter and ANKA platforms for testing purposes and the activities related to the trial are carried out by Meteksan Defense and subcontractor TAI. Deliveries are scheduled for April 2017, June 2018 and September 2019, respectively.

Helicopter MİLDAR's features are as follows:

  • Target detection tracking function,
  • Multiple target detection,
  • Slow and fast scanning,
  • High resolution and range resolution,
  • 12 km range for target detection and tracking in slow scan mode,
  • Low volume, weight and power requirements,
  • Real-time ARPO image,
  • Creating a land profile of 2,5 km in the mountains,
  • Navigation support
