这些RCS数据准确吗

Wolfhound0104

我觉得有些机型的RCS数据失准啊，大家都来吐槽下吧。

测量RCS是360度多方面的反射截面积算，不知道这种表格说明的数据是片面的还是平均的？
飞机所接受不同角度的雷达波辐射反馈出来的信息也是不同的，比如俯仰面照射显示的面积大，前后侧面照射反馈的面积小。比如T-50侧面反射面积小于F-22（不考虑吸波材料和等离子体因素，单纯几何反射截面作用），综合平均下来还是F-22反射截面积小于T-50

F15的也太大了吧

我表示非常不准确，看15和27的比较就能知道了。

AWACSs today like E-2C Hawkeye 2000 and E-3C are capable to the detect the target of RCS = 1m2 class 250~300 km away.

And their maximal effective detection range to the fighters in the world should be:

* F-15C & Su-27 (RCS = 10~15m2): 450 ~ 600 km
* Tornado (RCS = 8 m2): 420 ~ 500 km
* MIG-29 (RCS = 5 m2): 370 ~ 450 km
* F/A-18C (RCS = 3 m2): 330 ~ 395 km
* F-16C (RCS = 1.2 m2): 260 ~ 310 km
* JAS39 (RCS = 0.5 m2): 210 ~ 250 km
* Su-47 (RCS = 0.3 m2): 185 ~ 220 km
* Rafale (RCS = 0.1~0.2 m2): 140 ~ 200 km
* F-18E (RCS = 0.1 m2): 140 ~ 170 km
* MIG-42 (RCS = 0.1 m2): 140 ~ 170 km
* EF2K (RCS = 0.05~0.1 m2): 120 ~ 170 km
* F-35A (RCS = 0.0015 m2): 50 ~ 60 km
* F/A-22 (RCS < or = 0.0002~0.0005 m2): < or = 30 ~ 45 km

Even the tradional fighters (F-15, F-16) have the modern AWACS on their side, the stealthy fighter like F/A-22 with AIM-120 is still capable to give them the big surprise.

As for the low RCS NG fighters like EF-2000, MIG-42, and Rafale, if they are equipped with the NG BVRAAM like Meteor (Effective range: 90~100 km+ to the 9G maneuverable fighter, and 150~200 km+ to the big, slow and clumsy airplanes like AWACS...) and R-77M-PD (Maximal effective range: 160 km+), I think they also have certain amount of chance to give tradional fighters + modern AWACS today a surprise.

飞机所接受不同角度 ...

从B-52那性感的100㎡的RCS数据上我可以判断这是正面RCS数据。

AWACSs today like E-2C Hawkeye 2000 and E-3C are capable to the detect the target of RCS = 1m2 class ...

为何这些数据里台风的正面RCS依然比阵风的正面RCS低啊～唉。

台风前半球只有F-22能超过，在某些角度优于F-22？这个所谓的某些角度不会是只有零点几度吧？

谢谢你的数据。这里有段话令我很不解：
1. "The Typhoon's RCS is bettered only by the F-22 in the frontal hemisphere and betters the F-22 at some angles." (2001).
“台风前半球只有F-22能超过，在某些角度优于F-22？”F-22是按全向隐身设计的，台风虽然有后起优势，但真的能在某些角度优于F-22？难道是发现了F-22的设计缺陷？而且这段话也没标明出处，我还是持谨慎态度
