this is not about f-14 vs f-35, it's about radar range, i don't know why chinese radars have limited ranges (i'm not trolling i really want to know why, is it a tactic or what??).
for example if you could have a radar with 800 km range, it would detect an f-35 in 212 km away... so radar range matters.
This is a gross misunderstanding of even basic radar detection principles.
I will give you a real world example. The MIG-25's radar was so powerful in terms of amplitude and range that its signals can actually achieved 'burn-thru', meaning those signals are so powerful that they cannot be jammed. The signals will power thru any countermeasure signals.
This...
...Is the foundation of %99 of radar systems: A pulse.
What most people, and apparently including you, do not realize is that a pulse is a
FINITE packet of energy. A pulse have a leading edge (LE) and a trailing edge (TE) and that is what make it finite. The radar transmit and create an LE, then it stop and that create a TE. And repeat a few million times. The longer the pulse, the greater the amount of energy per pulse. Conversely, the shorter the pulse, the less the energy per pulse.
So why would anyone use shorter pulses? Because the LE and TE are effectively
TIMER markers. An LE have a time when it was created and the TE is the time when it ended. With these timer markers, the radar computer is able to generate these target resolutions:
- Altitude
- Speed
- Heading
- Aspect angle
The shorter the pulses, the finer the granularity of those resolutions. Conversely, the longer the pulses, the coarser those resolutions.
The MIG-25's radar was so powerful but so coarse that it could not do anything beyond telling the pilot that there is 'something' in a direction, in other words, the MIG pilot would not know those target's resolutions. But that was against a 'non-stealth' target.
Remember, the MIG-25's radar can only tell the pilot of a 'blip' on the radar scope, not how high, how fast, or heading.
Against the F-22 or F-35, in order to achieve the same target detection as that of the MIG-25 against 'non-stealth' targets, you would need a
PHYSICAL pulse length of
METERS.

Look at the VHF to the HF bands. The seeking radar would have to be in those bands. A pulse would literally have to be at least one meter length.
Then with that level of energy thru the ether, the F-22 and F35 would know where the EM threat is and take evasive actions before the seeking radar would know anything. This
TACTICAL knowledge is why despite decades passed since the F-117, long wavelengths radar have not proven to be the solution against 'stealth' that Russian salesmen have claimed.
So by all means, Iran can use those long wavelengths, high energy, and long range radars. See how effectively they will be, but by then, it will be too late for Iranian air defense.
And I have not even touched beamwidth.
blogs on nationalinterest say all kinds of things.. I wouldn't take them to seriously
You should. Because that is the intellectual lollipops your fellow Chinese needs on this forum. A lot of sugar but no real nutrition.
