Not to mention that long wave radars were pretty much only ones used throughout 40s and 50s, and had just fine succcess telling what is a bird and what is a plane, with little computer processing power. RCS is wavelength dependant, a plane that has a 1 sq. m rcs for cm wavelength radar will have several times larget rcs for meter class wavelength radars. Of course it doesn't make such radars a sure thing against stealth. Less precision can be dealt with to an extent, but their size is the biggest problem.

SinoForce sez;
SinoForce this is a very ludricous statement. The USN does not depoly any sort of drone decoys on their CVN's. Nor do they plan on doing so. Just where did you get this idea? Can you back it up with a link?
The USN does use target drones for "missile shoots"(firings) and war games. Not for decoys.

Notice that I typed "can" not "do".
He asked how many "can" a carrier battle group carry. So I responded that they "can" carry a lot. As you confirmed, they already use them for taget practice so there's nothing to stop them from sending them over enemy airspace as decoys if they wanted to.I know you're just tooling around, but you seem to underestimate how ****** Americans can be when on the offensive. The US military will tear china's air defenses apart. I'm sure America's enemies will buy more chinese/russian systems in the future and we'll see that they are going to get run over just as hard.So F-22 features a emergy shift which brakes the airspeed down to the level of bird flocks

If you give a monkey an AK-47 he'll want some ammo to go with it, but he'll probably get killed before he figures out how to pull the trigger. I don't see why other countries losing to us is really relevant.
I'm curious if YLC-20 is PCL or not. I'm also curious as to how extensive a radar network would conceivably have to be to lock-on and shoot down a stealth fighter. I would consider it far more practical to simply have the ability to detect stealth aircraft and launch fighters to intercept. Seeing how the PL-12 and AIM-120 have about the same range it makes sense to me.

Are stealth airplanes capable of absorbing radar waves, instead of just reflecting the waves not back to the source?
The stealth bomber try to reflect upwards much of the radar waves and also downwards but away from the source.
YJ-27 anti-stealth radar how does this radar work?

Modern stealth fighters are indeed capable of absorbing radar waves to applied radar absorbing material, or .
They also incoporate the technique to deflect radar waves away from the transmitter.
Those anti-stealth radars use generally very long wavelength to detect those targets. The wavelength is in the magnitude of the szie of that plane or even greater, wich makes it difficult to hide such an object from those long waves, I'f I'm correct.
Besides, that RAMs applied to aitcraft can absorb radar waves only in a specific bandwidth. You hardly can cover the whole spectrum on a plane.
However, the long wavelength makes accuracy a problem.

it's called frequency dependence. All you need to know is that various signals produce various returns given the same target.
Nothing tests equipment and training like actual combat. So if they get beat, then their equipment and/or training just wasn't good enough.If you give a monkey an AK-47 he'll want some ammo to go with it, but he'll probably get killed before he figures out how to pull the trigger.

The radar network would be so extensive as to cause the defenders to question the expense. Stealth fighters are effective because they force the enemy to waste a lot of money. It might come to the point that in order to defend against stealth, the air defense costs more than the target being defended.
That theory blows because the radar means to detect stealth, will cost you far less than than to develop, build, and maintain the stealth jets themselves. Do you know the kinds of materials that have to go into a stealth jet? Some of the maintainance procedures are so arcane, for example. If you open a panel to do some maintenance, the edge of the panels have to be caulked with a special compound when they are put back. Then it has to be dried at least a day or more. Then the section has to be repainted with RAM coating. During that time, the plane cannot be taken for missions.
The cost of a stealth jet, can range from 100 billion for a JSF to over 280 billion for an F-22. How much is an entire squadron? How much is the development money and resources used to develop this? How much does a radar network cost, if we are to implement long frequency UHF/VHF radar (like used so effectively in the Battle of Britain), and to implement multistatic radar. Multistatic radar does not need exotic scanning techs like PESA or AESA; it is possible to even convert existing radar sets into multistatic with component and software changes. Its possible to even use stray radio waves, for example, like the ones used by cellular phone repeating stations, as illumination sources. This is not to mention the third means too, using electrooptical scanners (IRST). And finally the fourth factor that may work against stealth is that DSPs and computing processing power is getting so good, they may actually get to filter and pick out the weak return signals that may be reflected off from a VLO target.
But of course, your fighters need extensive networking abilities, but networking is valuable in so many other ways, you're going to put them anyway.
Sooner or later, everyone has to invest counter stealth measures one way or another. It's not the fighters you should be worried about, but the creation of VLO cruise missiles or ballistic missile warheads, things that will cost you far less than any fighter.
