METEKSAN's MİLSAR Radar Gets a Long-Range Maritime Mode | TURDEF

METEKSAN’s MİLSAR synthetic aperture radar in use with UAVs has received a long-range surface search mode with a range of 90 nautical miles, about 165 km.

turdef.com

This is like a revolutionary upgrade to the MILSAR we knew that had an under 30km range.
This new version developed for Maritime use, specifically for Aksungur, will give an effective range of 90 Nm(166km). Aksungur can accommodate a tandem use version. It can also be used to give mid course correction to surface launched antiship missiles (land or ship launched).

The primary advantages include:

• Dual Capability in One Unit: The system combines high-resolution imaging (SAR) for stationary targets and tracking of moving targets (MTI) into a single, versatile package.
• Adverse Weather Operation: Because it is a radar system, MILSAR can operate "over-the-cloud," providing ISR (Intelligence, Surveillance, and Reconnaissance) capabilities in low-visibility, day-or-night conditions where Electro-Optical (EO) sensors fail.
• "Slew-to-Cue" Functionality: On larger platforms, the SAR and MTI can work together, allowing the radar to immediately shift focus to a moving target identified by the MTI mode, increasing efficiency.
• Operational Flexibility: MILSAR offers both Stripmap mode for wide-area surveillance and Spotlight mode for high-resolution imaging and classification of specific targets.
• Low Size, Weight, and Power : With a weight of less than 30kg, it is designed for easy integration onto tactical UAVs (e.g., Bayraktar TB2, ANKA) as well as larger platforms (e.g., Aksungur).
• Immediate Target Data: The system provides real-time data on target location, speed, and direction, which can be displayed on geo-referenced, digital maps for operators.

Because of it’s geometry it can be used in Tandem form from Aksungur;
Having a tandem MILSAR (Miniature SAR/MTI Radar) system, which integrates both Synthetic Aperture Radar (SAR) and Moving Target Indication (MTI) capabilities, provides several tactical advantages for unmanned aerial vehicles as pointed out above.

Dimensions (D x H)	37 x 44.5 cm
Weight	28 kg
Power	20-30V, 600W average
Max Altitude	22000 ft
MTI	Max range up to 90 nm depending on target Max no of targets: 1000 track capacity: 200
SAR	Max range: 15 nm Image resolution: 3 x 3m, 1 x 1m, 60 x 60 cm, 30 x 30 cm

This would also be great to pair with heavier USVs that can carry Çakır or maybe even Atmaca.

thats what Data link is for.
Plus Aksungur can carry at least 2 Cakir which have now 200 km range

Our TB2 are using the old radar, so basicly TB2 can be upgraded. What they should do is with this radar installing Cakir on Aksungur.

Tubitak bilgem F-16 ED pod.I have been skeptical about this pod because normally this kind of pods would be at two wings to secure pinpoint accuracy detection.This picture show us there is at least 4 may be 6 antennas to secure the problem in one pod.If roketsan make akbaba missile,we will have our wild weasel F-16.As far as I understand multiple antennas covers more than 180 degree.

Could the increase in Milsar radar's capabilities be due to its upgrade from a PESA radar to an AESA radar?

Will there still be a need for this EHpod once the Murad AESA-type aircraft radar comes into use?

I was against an EHpod without an AESA antenna system from the beginning. Because there is a huge difference in capabilities between old-type sensors and jammers and EW systems with AESA antenna systems.

We understood this difference in the Koral system. The simplest difference is called RF bandwidth.

How effective will the EHpod system be against AESA-type aircraft, ground and missile radars?

What is the noise in the radar picture close to the aircraft? Is it whether changes like clouds, or wind?

Could the increase in Milsar radar's capabilities be due to its upgrade from a PESA radar to an AESA radar?

MİLSAR is not explicitly described as a PESA (Passive Electronically Scanned Array) radar.
Instead, it is defined as a Ku-band Synthetic Aperture Radar (SAR) and Moving Target Indication (MTI) radar.

MILSAR is also not an Aesa Radar. Although Aesa radars have SAR capability to increase their operational range and ground image clarity especially above clouds, they are different.

Meteksan has a Retinar Aesa Radar to perform as an Aesa Radar.

• MILSAR: A SAR/MTI radar designed for imaging and target detection, optimized for UAVs.
• Retinar AESA: A separate radar system specifically branded and developed by Meteksan as an AESA radar for drone detection and surveillance.

Key Differences:

• Definition: AESA is a radar antenna type (hardware); SAR is a signal processing technique (mode).
• Function: AESA acts as a versatile sensor (air-to-air, mapping); SAR specifically creates photographic-like maps of the ground.
• Movement: AESA can function while stationary or moving; SAR requires movement to build its "synthetic" image.
• AESA Advantage: High-speed scanning, multi-mode functionality (simultaneously tracks air and maps ground), and low interception risk.
• SAR Advantage: Provides very high-resolution, all-weather imaging, often superior to optical sensors in cloud cover.

While MILSAR uses modern radar technologies for detection, Meteksan's specific AESA technology is marketed under their Retinar AESA product family.

Increase in range is the result of product development and technology upgrade. Also you need to note that it is not the SAR capability range that is improved. It is the MTI (target indicator) range that is extended to 90nautical miles.

Looks like weather, it can not only detecht enemy fighters but going to see it is going to rain...

Actually, looking at the antenna of Aselsan's SAR radar here, I think the SAR radar is a type of PESA radar. That is to say, it's a PESA radar that also uses Doppler signal processing techniques.

Of course, it's a radar that can obtain images by processing variables such as speed, distance, and time. The single signal source and multiple array receivers technique is the PESA operating structure.

For example, the Doppler radars of RF-4E aircraft can obtain SAR images. Similarly, the Israeli EL-M 2032 F-4E PESA radar is also SAR + GMTI capable. So, Meteksan's radar is fundamentally a PESA radar.

No,
Synthetic Aperture Radar (SAR) and Passive Electronically Scanned Array (PESA) represent two different aspects of radar technology, with the former describing an imaging technique and the latter describing an antenna architecture. (As far as I know, Aselsan do not have any PESA radars either).

MILSAR is not a Passive Electronically Scanned Array (PESA) radar. It is a multi-mode Synthetic Aperture Radar (SAR) and Moving Target Indicator (MTI)system.
While both technologies involve advanced signal processing, they serve different primary functions:

MILSAR (SAR/MTI) is designed specifically for high-resolution ground mapping and tracking moving targets from UAV platforms. It synthesizes a large "aperture" by using the movement of the aircraft to create detailed, photo-like images of the ground.

PESA refers to a type of phased array antenna architecture where a single central transmitter feeds multiple antenna elements. PESA is primarily a method of beam steering rather than a radar mode like SAR.

Both PESA and AESA radars can function as SAR. While PESA can perform the task, PESA radars generally have lower bandwidth and more signal loss compared to AESA, which can limit the quality, resolution, and speed of the SAR mapping. However some PESA radars can function as SAR like the Irbis on Su35, featuring SAR mapping modes with resolutions as fine as 3x3 meters. MILSAR has a resolution of 30cm in spotlight mode and 50cm in stripmap mode.

I got a question is YIRAD now known as alp600 or something else because of the size difference. YIRAD was shown to be similar to tpy 2 and alp 600 is as big as 4 story building.

Everyone been focusing on TÜBİTAK SAGE activities in the 2025 report, but BİLGEM been up to some nice stuff too in radar stuff

 

[MonteCarlo]

One interesting thing about YDYFR radar is that despite it being a "maritime surveillance radar" the Raytheon equalivent of it can detect and track but not target lock(because of low fidelity of the radar wave) F-35 sized aircraft from 80-120 km away and big passenger type aircraft from 280+ km away in daytime. Moreover generally is not effected by RAM painting and stealth geometry because of the huge wavelength of the radar waves(10-100 meters). I don't know if TÜBİTAK is working in this area for this project but can serve as a nice tripwire system against stealth platforms

We actually have the ALP 400-G development for that end, but the spaital resolution isn't impressive on its own due to the operating band. Thus, it works better when paired with higher frequency radars like ALP 300-G/ALP 100-G or optical sensors
