Radar Doppler Multitarget


Radar Doppler Multitarget is a multimode Look-down/shoot-down Pulse-Doppler radar designed by Thomson-CSF 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.

Design

The original RDI/RDM radars on the Mirage 2000 only worked in air-to-air mode. The RDY was designed to add air-to-ground modes, in particular the ability to control Exocet and Kormoran 2 anti-shipping missiles. The system has a flat-plate antenna scanning a 3.5° beam over a 60° cone at powers up to 120 kW. Maximum range is in air-to-air mode and in look-down mode. The RDY can detect 24 targets, track eight of them and engage four targets at a time. The enhanced RDY-2 has a slightly greater range and adds a SAR mode.

History

Development began in 1984, with the first of nine prototypes flying in July 1987 in a Mystère 20, and the first delivery of a production set in December 1994.
RDY is the standard fit on the Mirage 2000–5,-5Mk2 and -9 aircraft and has been retrofitted aboard 37 French Air Force Mirage 2000Cs, 25 Greek Mirage 2000-5 Mk2 and 62 United Arab Emirates' Mirage 2000EAD/DADs. Other customers for the Mirage 2000-5 include Qatar and Taiwan. India's fleet will receive RDY-2 under a €1.47bn contract signed in July 2011 to upgrade them to 2000-5 standard.
As part of the MF2000 upgrade, 27 Mirage F1 of the Royal Moroccan Air Force are being fitted with the Thales RC400, a derivative of the RDY with an antenna sized to fit the smaller aircraft.
