The Russians—as Center for Naval Analyses research scientist Michael Kofman noted—have had infrared search and track sensors onboard their fighter aircraft for decades. Even the earliest versions of the Mikoyan MiG-29 Fulcrum and the Sukhoi Su-27 Flanker have had an IRST system installed. The Russians have continued to field modern fighters such as the Sukhoi Su-30SM and Su-35S with newer and more modern IRST technology even if the detection ranges are fairly unimpressive. Even the forthcoming Su-57 PAK-FA incorporates the 101KS-V infrared search and track system. “Like every Russian plane has a giant IRST pod in the front for the past 30 years,” Kofman said.

However, it is unclear what infrared wavelength the Russian systems use—but it is likely that it uses mid-wave infrared. Most military airborne infrared sensors tend to use middle wavelengths because of the good compromise between range and resolution capability. Long wave infrared was typically less common because while that part of the spectrum offers excellent range capability—and the ability to pick up extremely cool objects—those sensors were traditionally limited by poor resolution and clutter. However, the advantage is that a good long wave infrared sensor will be sensitive enough to pick up the heat generated by the disturbance of the airflow and skin friction of an aircraft travelling through the atmosphere.

Najverovatnije da se kod OLS-50M radi o dugotalasnom IC-dijapazonu (talasna duzina 15 mikrona)

И где њему очита циљ, на којем показивачу?

MarKhan ::И где њему очита циљ, на којем показивачу?

Recimo ako jedan monitor ocitava podatke sa radara ,drugi moze sa toplotnog pelengatora tj od OLS-50M .Na oba monitora pilot dalje prati osnovne letne parametre itd ..

Isto tako postoji mogucnost u slucaju otkaza jednog od ovih monitora da se jedan podeli `u dve celine` gde ce jedna pokazivati radarske podatke a druga podake od 101KS-V .

Kao što si se zapitao u toj poruci, sigurno je u kombinaciji sa UV senzorom i to monofotonskim koji radi u pojasu 250-280nm. Već je u primeni na LPRS Verba, a ovaj je sigurno bolje rezolucije i ima digitalnu obradu slike.

Onda se moze reci da 101KS-V u kombinaciji sa 101KS-U i posebno 101KS-O pokrivaju sve rakurse tj polusfere aviona radeci bilo u IC,bilo u UV-dijapazonu .

Dakle imamo tu onu `visespektralnu sverakursnu` pokrivenost ,radarsku te ovu od optoel. senzora .

Tako je.

Kad smo kod dugotalasnog IC-dijapazona

Citat:The 101KS-V is also sometimes referred to as the OLS-50M which is an advanced IRST based on the revolutionary Quantum Well Imaging Photodetectors ( QWIP ) technology. These new generation IRST systems have the potential to operate in a much wider spectral bandwidth that includes the very longwave 15 micron band to detect very cool targets. They can also be made to operate simultaneously in several different bandwidths.

Citat:Long-wavelength infrared
Wavelength:8–15 µm
Frequency: 20–37 THz
Temperature:362–193 K (89 – −80 °C)

Citat:В этом диапазоне начинают излучать тела с температурами около нуля градусов Цельсия. В этом диапазоне чувствительны тепловизоры для приборов ночного видения.

Za srednje talasni /3-8 µm/ :

Citat:В этом диапазоне начинают излучать тела, нагретые до нескольких сотен градусов Цельсия. В этом диапазоне чувствительны тепловые головки самонаведения систем ПВО и технические тепловизоры.

Ako se ispostavi da je ovo u OLS-50M pa on ce lovce na Maksimalu u PPS moci da otkrije sa pozamasne daljine a kamoli na Forsazu .Verovatno radi na obe ove talasne duzine, srednjoj i duzoj .Za poredjenje ,OLS-35 (srednja talasna duzina ) otkrije lovca na Maksu u ZPS sa 70km u PPS se nekih oko 50km ,u PPS/ZPS na forsazu sa 150-200km .
