The diameter of the radar in post 105 looks quite small, smaller than typhoon. How much smaller is the Rafale scanner in diameter when compared to captor/ECR-90?
Edit info from Internet......
Actually... the diameters are
F-20/T-50 => ~500mm (APG-67 family)
F-15 => ~950mm (APG-63, APG-70 families)
F-16 => ~660mm (APG-66, APG-68, APG-80 families)
F-18 => ~700mm (APG-65, APG-73, APG-79 families)
F-35 => ~700mm (APG-81)
F-22 => ~900mm (APG-77)
Gripen => ~500mm (PS/05 family)
M2000 => ~500mm (RDM, RDI, RDY families)
Rafale => ~600mm (RBE family)
Typhoon => ~700mm (ECR-90/CAPTOR family)
MIG-29 => ~624 mm (N019, N010 families)
SU-27/30 => ~1000 mm (N001, N010 [924mm antenna ver], N011 faimilies)
MIG-31 => ~1400mm (N007 family)
In general, the radar aperture (antenna area) doubles with a 1.41 times increase in diameter. With all else being constant it takes an increase in aperture of 10x to double the range of a radar. Technologies like AESA antennas increase the output and sensitivity of a radar for any given size. Advanced T/R module technology and smaller T/R modules also do that. PESAs generally reduce sensitivity. Both types of ESAs allow instantaneous beam steering and high beam focus. Only the AESA can form multiple beams simultaneously.
The problem with radar improvements is that while output and sensitivity gains have increased radar performance by about 20~30x in the past 30 years translating to an increase in range for a given physical aperture of up to 2.6 times. The advent of VLO airframes has reduced RCS to roughly 1/1000~1/10000th that of 4th generation jets. To make up for this through radar improvements will require an improvement of radar performance by 1000~10000x which is not projected to be possible with known and projected technological road maps.
