Thanks, That make sense. But could you tell how did you calculate 2.8x maximum range increase? I am seem to be getting 2x only (For the nose array comparison) using the formula AESA radar calculator developer gave.
((2304/1152)^3*(60/30))^(1/4)
=2.
Both aperture area and output power affect the radar range.
The number of TR modules alone has no direct effect. The number of TR modules is only important if it affects the total output power or aperture size.
Rmax: Maximum detection range (meters)
Pt: Radar transmitter power (watts) (1x for radar 1, 4x for radar 2 1152X30 vs 2304X60)
G: Radar antenna gain (dimensionless)
λ: Radar signal wavelength (meters, same for both radars so not important when comparing)
σ: Radar cross-section / RCS of the target (square meters, same for both radars not important when comparing)
Pmin:Minimum detectable signal / receiver sensitivity (watts, I assume the same for both radars unless Murad-600A is more sensitive)
Ae: Aperture area (1x for radar 1, 4x for radar 2)
We rearrange formula 1 and write 1 in place of
λ, σ. Since Pmin is also the same for both radars, the denominator can be removed.
Rmax ∝ (Pt.G^2)^1/4
G is directly proportional to Ae because
λ is same for both radars.
Rmax ∝ (Pt.Ae^2)^1/4
Increase Pt to 4Pt and Ae to 4Ae (4Pt.4Ae^2)^1/4
(4Pt.16Ae)^1/4= (64)^1/4= 2√2= 2.828
When everything else is the same a radar that has 4x output power and 4x aperture area has 2.828 more range compared to the baseline radar. Of course this doesn't take into account real life lossess that might come with a bigger aperture size and more power pushed down a module.
If we only increase power 4x detection range only increse by 4^1/4= 1.41 times
If we only increase aperture area 4x detection range increase by (4^2)^1/4= 4^1/2= 2 times.
