ECR-90 Captor radar
» multi-mode pulse-Doppler radar
» resistant to active and passive countermeasures
» incorporates IFF with interrogator and an advanced Mode S
transponder
» automatically tracks, identifies and prioritises threats
» interleaves air-to-ground and air-to-air modes
» air-to-ground mode has multi-target track, scan, raid
assessment, non co-operative target recognition and close
range combat sub-modes
» air-to-ground mode has beam-sharpened ground mapping,
synthetic aperture radar (SAR), moving target indicator and
terrain avoidance sub-mode
Which of those modes are currently implemented? Can we assume that none of the air-to-ground modes are available?
