No slight to China but it seems curious to me that since the F-22 is in full service we are seeing equipment that can defeat it. Including aircraft..curious. How do the test this radar when they don't have a 5th generation aircraft themselves??:confused:

For bistatic passive radar, I don't see why they even need a stealth target to test it. Stealth aircraft works by deflecting most of the wave at an angle. This means the radar deflection from off axis angle may even be greater than non-stealth aircraft, and the off axis deflection is exactly what bi-static radar used to locate the target. Stealth aircraft absorbs some radar signal due to material or wave trap -- this can be simulated by attenuating the radar signal.

I think it involves more than just being able to detect small signatures. How many sparrows size objects are there in a 80 Km radius?

What else is there? Detect, track, fire missile...

Do you mean any counter stealth radar should be able to track a large number of targets too? (can't think of anything else)

How may sparrow sized target fly at typical aircraft speed? Modern radars uses Doppler Effect to filter out most of the clutters.

JY-11B ()or type-304 radar) took part in the parade, the TV may be refering to Type-305 L-band AESA surveillance radar.
the first picture appear in the chinese website in 2005.

Here are some Anti-Stealth/low observable detection equipment :

1st one looks a bit like the the Czech Vera system -
2nd & 3rd are JY-27 -
Don't know the designation of the last two -

I think China put together a cruise missile with some faceting and non-metallic, carbon composite based skin like what most current airplane used.

Something like this should able to simulated a F-22

I know about aircraft and but little about radar, especially bistatic radar. I was thinking about small passive radar aircraft operating from small ( 20 000 tons? ) aircaft carriers. Such aircraft carriers might be built without intimidating anyone.
The illumination might then come from long range high flying ( 20 km ) unmanned emitter aircraft. They would encode their position and the time in their radar emissions.
Such aircraft might operate for days, having no crew, but would need more power than can be delivered by solar cells.This is one of the very few aircraft than can make use of hydrogen fuel. The aircraft might be based in Tibet, with easy access to the Indian Ocean over Myanmar or Pakistan.
The hydrogen might be generated by electricity generated by wind turbine fields around the bases as well as possibly water power. The basic needs of the basis and possibly of villages or mining in the neighbourhood have priority but any excess goes to fuel production.
To save weight and drag the radar antennae are mounted in the leading and trailing edges of the wings. For good altitude discrimination the aircraft are to be biplanes, The first modern biplanes since 1947.
