Airborne IRST properties and performance

Introduction IRST is a sensory device which uses IR (infrared) radiation for detection and targeting purposes. IR radiation has wavelength of 0,75 to 1.000 microns (micrometers), longer than wavelengths of color red in the visible spectrum (visible spectrum ranges from 0,39 to 0,7 microns, with violet at 0,4 and red at 0,7 microns). It is … Continue reading Airborne IRST properties and performance →

OSF

IRST Range v/s subsonic fighter aircraft: 80 km from front, 130 km from rear (20.000 ft), 110 km from rear at low altitude Visual camera Range v/s fighter aircraft: 45 km Laser ranger Range: 33 km https://www.thalesgroup.com/sites/default/files/asset/document/OSF_UK_060208.pdf http://www.flightglobal.com/news/articles/tests-begin-on-rafale-optronics-50879/ IRST ID range may be 40 km.

PIRATE IRST

PIRATE IRST is IRST sensor used by Eurofighter Typhoon. It is FLIR, which means that it can use IR radiation to assemble a video image, similar to night vision devices and infrared cameras. Technological data is as following: Detection range against typical subsonic fighter target: 90 km from front (head-on), 150 km from rear* Identification … Continue reading PIRATE IRST →

Cleaning up Red Flag Alaska F-22 vs Typhoon debate

Since Eurofighter Typhoons defeated F-22s at Red Flag Alaska in June 2012, discussion has produced many claims. I will address some of them here: 1) WVR combat is only small spectrum of air combat. Yes, and no - it mainly depends on numbers, and who you are shooting at. As enemy numbers, as well as quality of … Continue reading Cleaning up Red Flag Alaska F-22 vs Typhoon debate →
