Two new Ukrainian radars were noted briefly in September 2015. These were the 80K6T series and the DNEPR [?????], not to be confused with the DNEPR series of ATC radars nor the Russian OTHR system. Since then more information has come to hand. There are a number of 80K6 variants. The base model 80K6 is normally on a towed trailer. 80K6K1 is a self-propelled version that employs a two-vehicle convoy. Then there is the 80K6M, again self-propelled by either a single MZKT truck chassis or an optional KrAZ chassis. This version is said to have been developed to be in direct competition with the Westinghouse AN/TPS-75 and the Thales GM400, although at a more favourable purchase price according to the source.Moore’s Law and Radar Improvements
The basic model has been purchased by Azerbaijan, India and the United Arab Emirates. The 80K6M is reported to have achieved undeclared exports whilst the 80K6T is now operational also in the UAE. Coming back to the base model 80K6, this radar has also been deployed to enhance the Ukrainian air defence network and whilst dispositions have not been reported, U-Tube video suggests there are four units deployed in the vicinity of Shchors (51°50'49.92"N, 031°48’54.21"E) Rubizhne (48°54'25.42"N, 038°32'35.15"E), Artsyz (45°56'32.94"N, 029°22'59.79"E and Stryi (49°14'44.99"N, 023°46'59.65"E ).
The 80K6 series all operate in the EF-band region and have interrogators with an RF centred on 668 MHz. Other parameters have not been declared except that we know the system employs a 12 or 16 channel passive phased array with a claimed range of 400km against airborne targets flying in the region of 30-100 thousand feet altitude, which might suggest a maximum PRF in the region of 375pps. A minimum range of 6km would suggest a transmitted pulse of about 40μs, so some type of waveform compression must be employed. Whilst the radar antenna can be mechanically scanned it is apparently more commonly held on a target bearing of interest and electronically scanned over an arc using digital beam forming techniques fed by a high-gain Klystron. Notably, however, some reports suggest the outputs are in analog format. These radars are all manufactured by ISKRA in the Ukraine whose website is <www.iskra.zp.ua>
Moore’s law basically tells us that computing power doubles at regular intervals. It relates to how many transistors can be squeezed onto a chip, which in turn is linked to electron transit times, where the smaller the gap the faster the result and the greater the number in a finite package. Advances in technology have aided this process but it may now be coming to an end, or is it. The Raytheon Company, foremost among others has been researching and developing gallium-nitride components for military purposes for some years. It is a technology that might also benefit consumer technology. If you would like to learn more, please see:
