Radar Doppler Multitarget (RDY in its French acronym) is a multimode Look-down/shoot-down Pulse-Doppler radar designed by Thomson-CSF (now Thales) for the Mirage 2000-5 fighter. The RDY-3 derivative has been fitted to Moroccan Mirage F1s. Thomson has claimed that the original RDY outperformed the AN/APG-66/68 of the F-16 and the AN/APG-65 of the F/A-18 Hornet.[1]
