China says it has developed a new radar system that can spot US stealth fighters...[truncated]

China has reportedly developed an over-the-horizon maritime early warning radar system that its creator claims can detect stealth aircraft far beyond visual range, an advanced capability that could threaten US fifth-generation fighters operating in the area.

Liu Yongtan, the team leader for the radar project, told Chinese media his high-frequency surface wave radar emits "high frequency electromagnetic waves with long wavelengths and wide beams" that travel along the surface of the sea, the Global Times reported Monday, citing a recent interview with Naval and Merchant Ships magazine.

The radar system, part of China's ongoing efforts to prevent a sneak attack by enemy stealth assets, can purportedly detect enemy air and naval threats hundreds of kilometers away in any weather condition.

Did a search but didn't see this posted.

My first question is about this tidbit;

Liu Yongtan, the team leader for the radar project, told Chinese media that the radar emits high-frequency electromagnetic waves with long wavelengths and wide beams that stealth assets are not protected against.

So...does it use high frequency waves or does it use long wavelengths? Apples and oranges as far as I've been taught.

High frequency = shoort wave lengths

I’m wondering how they changed the laws of physics.

First I don’t believe this.

BUT:

Lessay they CAN vector fighters for intercept:

Can those fighters lock on?

Can those fighters get missiles to bring down our planes..?

That’s lots harder.

Tracking and targeting and DIFFERENT.

I have read, in the past,that stealth planes can be detected and located through reflecting cell phone signals. It’s probably similar to that.

May I axe a question?

If China {or any country} had developed such a unique ability, would they publish a report about it?

Why warn your enemy about your advantage?

I do not believe a single word of this story.

Even if this is bogus, it will happen sooner than later. I don’t understand why the US Military does not crank on drones for these types of missions. In one sense, who cares if a drone gets spotted and shot down if you build thousands of them.

Yes...plus if this is true...WHY WOULD THEY BROADCAST IT?

I hope we have a few hundred thousand unmanned cheap plywood drones we could swarm them with.

Let them fire all their ammo at those first.

Yup, doublespeak. Actually detecting stealth isn’t all that hard. I am not saying how in public.

Two points:
1. The Chinese are not exactly innovators. Not much “ne has come out of China in centuries. Color me skeptical.
2. The radar system, part of China's ongoing efforts to prevent a sneak attack by enemy stealth assets
When was the last time anyone on earth attacked China? (Japan, 1942... 77 years ago)
3. When is the last time anyone on earth attacked a major power with stealth assets? (US and Russia have taken photographs... but the only ones ever attacked by stealth assets have been unstable Middle Eastern countries.)

Seems like an expensive solution for a problem that doesn’t exist.

Read about this YEARS ago...

Basically, at least the article I read years ago, was it found the “voids” rather than looking for reflection... and the VOID was the plane.

And this was A LONG time ago... not recently I read this.

"Actually detecting stealth isn’t all that hard. I am not saying how in public."

And jamming radar? Targeting radar?

The same way they have created the UFO’s being reported by our military pilots who are part of the new History Channel series, ‘Unidentified,’ (no agenda there, eh).

But seriously, there is literature in the public domain about ways to defeat the new low radar cross section aircraft design. The trick to low RCS is absorbing the radar energy or reflecting the radar energy in directions other than back at the radar emitter. One way to defeat this is to use whats called bi-static radar, where the radar receiver and transmitter are not co-located. IF one could locate the receiver where the reflected energy is sufficient, THEN you could conceivably detect the low RCS aircraft. But that may be harder than it seems, since that would imply you have a good idea where that reflected energy is going, which would be a function of the aircrafts design, heading, and attitude, and the target was not smart enough to account for this in its tactics.

Do I think the Chinese have developed such radar? Maybe, but I doubt it. Will they? In time, all technology becomes dated and the stealth technology someday will seem primitive. By then, we should be on to the newest and latest technology with the Chinese still trying to play catch-up.
