@Test7 bro, Can we enlarge this triple anti-drone-like system called Şahin?

When can Turkey expect a 1280x720/1024 MWIR FPA ready for testing and then serial production?
It depends. Resolution is important but so is pitch length. If you go for example 30μm process it will come out early without any issues but the overall die size will be bigger. A bigger die size means a bigger optic and a bigger system. We can see a 1280x7201024(15μm) die very soon if we scale up the current 640x512(15μm) die. We can put it on a 22" gimbal and it will fit quite well to Akıncı and Aksungur. With this, we can get crystal clear images from insane distances at this gimbal diameter. Once you master a process it is easier to come up with a product family. Aselsan will release an MCT product family in LW and MW. 1280*720 die will also fit on the existing CATS system but 1280x720 dies are overkill for the UAVs like TB2 (Wescam also offers 640x512 as standard and 1280*720 as optional for their MX-15). As a guesstimate, I would say late 2023 at the earliest for the production of a 22" 1280*720 FLIR. EOTS (Electro-Optical Targeting System) of the MMU will also use 1280*720/1024. There is also dual-band(MW+LW) products.



This is released in May 2018 and it is behind a paywall but the summary tells a lot.



ASELSAN A.S., the largest defense company in Turkey, initiated research activities on developing Mercury Cadmium Telluride (MCT) detectors in 2014. These research activities include bulk crystal growth and surface preparation of Cadmium Zinc Telluride (CZT) substrates, Molecular Beam Epitaxial (MBE) growth of MCT layers, MCT detector fabrication, Read-Out-Integrated-Circuit (ROIC) design, and detector-dewar-cooler (DDCA) assembly development. Focal plane arrays with resolutions/pixel pitches of 320x256/30 μm and 640x512/15 μm are fabricated. Noise Equivalent Temperature Difference (NETD) of 320x256 FPA is 11 mK (f#/1.5, 77K) while the operability is 98.2%. 640x512 FPA provides NETD of 32 mK (f#/1.5, 77K) and the operability is 93.2%.

The long-term plan is to get to the 10μm pitch length. Sofradir is the only company I know that produces dies in this class(kinda like TSMC 5nm). Maybe there are one or two companies other than Sofradir that joined the 10μm club recently. Anyway, 15μm is a good modern process. If we go with the TSMC analogy it is kinda like TSMC 7nm.



By the way, the new Aselflir-500C is specially designed for UAVs. It has a SWIR sensor on top of an MWIR. SWIR sensors are very effective in bad weather conditions(fog, clouds, rain, etc) and provide good images.

There is a large market in Turkey for HD resolution thermal imagers. TB-2/3, Anka, Aksungur, Akinci, Mius, T-629, T929, Sungur on APC, ULAQ SIDA and perhaps upgraded versions for the Hisar family, naval IRST, targeting pods etc. + potential export market. This market could easily reach 1000 pcs or more, with a $1 billion market.

True. There is an ever-increasing market. This is why Aselsan started investing in big production facilities as early as 2016.
