Reference excerpt

Khibiny (L-175V) (Хибины) (Л-175В) is a Soviet / Russian aircraft electronic countermeasures (ECM) system. The name refers to Khibiny Mountains. The system is designed for radio direction-finding and probing signal source irradiation allowing it to distort reflected signal parameters. This helps to

Delay aircraft detection; Mask the true subject against false reflections; Cause range finding difficulties, namely in speed and angular positions; Degrading Maintenance Mode TWS when scanning antenna beam radar; Increase the time and difficulty of capturing an object during real-time active scanning; Create "false electronic situation", meaning to create electronic "clones".

History The first work related to the creation ECM "Khibiny" began in the Kaluga Research Institute of Radio Engineering; (Russian: Калужский научно-исследовательский радиотехнический институт) (КНИРТИ)) in 1977. The plan was to create a unified set of electronic countermeasures for all the armed forces, where the tasks for KNIRTI was to develop SIGINT blocks of equipment "Proran" and radio jammer (RJ) "Regatta", which was successfully completed with protected of scientific research in 1980. In 1982 KNIRTI was entrusted with research and development activities, first with "Proran" and "Regatta", and after an ECM as a whole, which includes many developments on related topics (including the use of accumulated experience in the development of RJ " Sorption ", which was planned to be installed on the Su-27 ). When started research and development with new ECM, later named "Khibiny", it was intended to unite all the units, ensuring that they work closely with the Jets avionics.

The first samples of "Khibiny" were far from ideal since their weight and size parameters weren't suitable for installation on the Su-27M. To solve this problem KNIRTI collaborated closely with Sukhoi, working under the direction of Rollan G. Martirosov. Collaborate on a plane integrated ECM (received code "product L-175") bore little resemblance to the conventional practice in such cases. Typically, the manufacturer of equipment issues to aircraft design bureau specification for the placement of products that represent a complete set of design documents and makes recommendations on placement of its parts with the restrictions on the length of the connections between them. In this case, the equipment "Khibiny" was immediately inserted into the design of the aircraft under development. Consequent to close co-operation by the end of the 1980s the first stage of R&D was completed and prototypes were made, due to delayed development the L-005S Sorbitsya-S was made as an offshoot, like the Khibiny it also used an AESA horn antenna for ECM transmission (although the big difference between the three was that Khibiny used digital signal processing whilst Sorbitsya used analogue). March 18, 2014 was adopted the fighter-bomber Su-34, equipped with electronic countermeasures complex L-175V "Khibiny". Upgraded Khibiny EW complexes join air units in course of modernization. According to TASS, the "Khibiny" complex will be further modernized based on combat results of Su-34 front-line bombers during their combat deployment in the Russian invasion of Ukraine. Features of the ECM system include.

False target generator Track breakers Frequency agility countermeasures Global navigation spoofing DRFM The SAP-518 or SAP-14 active jamming pods (or using the N035 Irbis antenna as part of Khibiny-M) have various jamming options available.

Sweep jamming Pulse jamming Continuous wave jamming Power managed jamming Noise jamming Also in 2014 when a Russian jet flew over USS Donald Cook, it created fake electronic signatures of additional targets. The current model is the Khibiny-M which utilises GaN based AESA antennas for ECM transmission. On 12 September 2022, Ukrainian forces claimed to have recovered a RTU 518-PSM jamming pod which is a part of the Khibiny-U system. It was found in the wreckage of the Su-30M near Izyum. The Khibiny-U system had been designed for the SU-30SM.

Variants L-175 Khibiny used on Su-27M, Su-30 and Su-32. L-175V Khibiny-10V used on Su-34. L-175U Khibiny-U used on Su-30SM. L-265M10 Khibiny-M used on Su-30SM2, Su-34M and Su-35S.

Worked examples

Example 1 — a first encounter with Khibiny (electronic countermeasures system)

Start with the simplest possible case. Write down what Khibiny (electronic countermeasures system) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Khibiny (electronic countermeasures system) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Khibiny (electronic countermeasures system) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Khibiny (electronic countermeasures system)

In research: Khibiny (electronic countermeasures system) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Khibiny (electronic countermeasures system) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Khibiny (electronic countermeasures system) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Electronic countermeasures, Electronic warfare equipment, Military electronics of Russia, so understanding it makes those chapters shorter.
In everyday life: Look for Khibiny (electronic countermeasures system) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
