????
Who tell you fga-35 is dual band ? if it is dual band then what is the frequency range?
and for your information, all fire control radar are 3D radar, 2D one are only used in early warning. You can have a 3D radar even with horn antenna

Electronic scanned array whether AESA or PESA, using GaN or GaAs cannot scan pass 60 degrees boresight, because at that point their beam forming using wave interference no longer work, there is a limit for phase different
N036 are in fact several group of separate ESA, not a single one.

If the beamwidth cover 90 degrees the radar would be useless for how inaccurate it is

ES-05 is an AESA that was put on a movable plate, the field of regard has nothing to do with whether the radar uses GaN or GaAs modules
The same case for the new AESA on Typhoon or Irbis-E on Su-35, they do not use GaN but they have big field of regard because they are on a movable plate, that it

So what you saying is that, they use visual light ? because that exactly what photons mean.

RCS of human according to global security is 1 face is less than 1/10 the size of the whole human body along with mass and weight. So my estimate seems it can detect an RCS at less than .1 from 400km. .
So how big is that ROFAR ? what is the average power?
Because TPY-2 can have that kind of detection range too, despite not using magical photonic technology
wewuzkangz2 wrote: RCS yes its also measured in decibels for noise. Its just multiple articles saying the same thing that relate to AUS APs charts.
If you don't understand what iam talking about then dont try to put some random terms together and pretend like you do.
The fact that many blog and forum uses the same figures as APA charts doesn't mean anything, as they all delivered using the exact same method, which is took one detection range vs RCS value then extend it into a curve using radar equation. That kind of estimation doesn't take into account minimum detectable signal or the SNR standard for the initial value that manufacturer uses, let alone others factors like radar mode used.
APA cannot even get the T/R elements count of APG-81 and APG-77 correctly and you want us to take their estimate serious?
APA estimate is 1000 elements for APG-81 while the real value is close to 1676 T/R modules
