J-20 5th Gen Fighter Thread VIII

its now GaN-on-Sic radar.. which is way way ahead in comparison with base version GaN.

Hence is it reasonable to assume that the current J-20A radar should have a significant advantage over the first generation radars being rolled out by other nations, including Kaan and presumably F-35 blk4?

I mean, I posted the stuff about Gan-on-Sic radar a couple of month ago. it is said to be 3x for the original J-20 radar.

I've encountered some articles on the topic as well: these are the developments I was referring to when mentioning the multiple-fold improvements in performance over baseline GaN radars.

as per @tphuang analysis, J-20A radar is at least two generation ahead in comparison with current F-35 radar.

Turkish radars are that good? Have they achieved any breakthroughs that would allow them to surpass the performance of Western radars and reach the same level performance as the latest Chinese radars?

I wrote the word "potential" with bolded letters for a reason.

All the articles we see about advances in diamond substrates and GaO coming out of China make me think China's sensor advantage will likely hold for the next decade or two.

Actually, the potential is being blocked by cooling restrictions, which Gan-on-Sic technology could unlock. Hence if the range statements are true, the latest J-20 radar might very well use Gan-on-Sic.

Why would it just hold, though? If anything, given the trajectory of China's innovation ecosystem, I expect that gap to widen.

I meant what tphuang wrote on it..

I meant what tphuang wrote on it..

I mean they said

在国防领域，碳化硅的突破直接关乎国家安全，团队研发的高纯半绝缘碳化硅成功应用于相控阵雷达核心器件，使探测距离提升3倍，让中国雷达实现“先敌发现、先敌制胜”，从歼-20的机载系统到尖端武器装备，这片“中国芯”承载着国家安全命脉，它让中国雷达看得更远、导弹打得更准、激光武器威力更强，成为国防科技不可或缺的“硬核盾牌”。

that's all I have on this topic. I don't know enough to say too much more except that we also got news on GaN-on-diamond being tested out. I'm just a guy following technology online.

If you are looking at how much difficult US Is having with even putting APG-85 on F-35, PLA's advantage here is going to be pretty large for a few years.
