just raw range and power isnt the only yardstick, sophistication also counts and in this the leading western radars have always been better - one of the reasons why we went to time and expense of developing the back end of Bars ourself.
I would not be surprised if the 2000-5 RDY was the RDY-2...
ne ways here is a quick refral of the two radars which were pitted against each other........
Thomson-CSF/Detexis quote the look-up,look-down, shoot-up,shoot-down performance as being 70 km. In actual practice engagements conducted by the French AdlA, RDY has demonstrated it´s ability to detect, reliably, fighter size targets at 140 km.
N001VE fire-control radar
orignal range 100km, engage 2 targets simultaneously
these two radars are very closely matched... even though the RDY radar says it has a 140 km range one has to understand that it is for detection only.. the track range is 70kms...i am not too sure of the N001VE track range... but ne ways these two radars do seem to be verry closely matched... except for the fact that due to its inherently large size the su-30 would be a bigger radar target ...aand due to a bigger radar would radiate more energy..
From Su-27 Flight Manual
The range RLPK in the free space and in lookdown engagements is practically identical and depends on the flight altitude of aircraft, hemisphere of attack and comprises, for a fighter (RCS = 3 sq m):
a) in flight of aircraft at high altitudes (more than 8500 m):
- in ZPS [rear hemisphere]
with the lookdown attack Search = 30-40km; Track = 30-35km;
with the lookup attack Search = 50-55km; Track= 45-50km;
in PPS [front hemisphere] the detection ranges are comparable to ranges in flight at medium altitudes;
b) in flight of aircraft at medium altitudes (more than 1000 m)
- in PPS Search = 80-100km, Track = 65-80 km
- in ZPS Search = 25-35 km, Track = 25-30 km;
c) in flight of aircraft at the low altitudes (200 m):
- in PPS Search = 35-40 km, Track = 28-32 km
- in ZPS Search = 20-25 km, Track = 18-20 km
Regarding the IRST:
Detection range against a military thrust fighter target in the rear hemisphere (0/4-2/4) is 50km against a pure sky background, 20-35km against ground, water or cloudy background.
In 1/4 aspect (directly behind), with the target in full afterburner, range is 90-100km.
Lock-on range is 70% of detection range.
Head-on range (5-15deg offset) is only 10km. The manual says to increase detection range the pilot should increase offset angle.
