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 range: >40 km
Maximum number of targets that can be tracked: 200
Ability to prioritize targets: yes
Field of regard: 140 ° in azimuth
Angular resolution: better than 0,05 °, some sources give 0,0143°
Against a fighter supercruising without afterburner at Mach 1,7, detection range will be 10% greater, resulting in range of 100 km from front and 165 km from rear. Comparing it to OLS-35, it should be able to detect AMRAAM launch from 173 km, and Mach 4 AMRAAM from 154 km.
*150 km is rounded figure, actual figure is 145 km
CAPTOR has angular resolution of 0,05 ° at 165 km, and PIRATE is better than that
