    If the US wanted to take-out PRC's OTH Radars they won't need the F-22 or F-35. They'll just fire 100s of Air/ship/sub launched cruise missiles. I mean even the good old AGM-86 and BGM-109 have ranges easily exceeding 1500 km. Actual ranges are classified but even the official range is at least 1500 km. The USAF bombers won't have any SAM threats at those ranges and the USN can stay outside the ASCM and ASBM ranges.

    Ok, to get back on topic, anyone has any new info on the gigantic JL3D-91B radar?

    We have now seen the YLC-8B, JY-27A, but little on the JL3D-91B

    Nothing ... but bthe topic is "Chinese Radar Developments - KLJ series and others".

    But I agree with you this discussion and the latest post fit better into the Aerial Defence Radar topic (if such one exists?).

    There is an Anti Stealth Radar thread title right there even next to this as I type.

    Has there been any new or confirmed information on the PESA radar used on L-15/JL-10 variants such as those L-15Zs exported to Zambia? They will seen fairly unknown, AFAIK I haven't even seen any source with a name for the system?

    Here is the documentary on doppler pulse radar development and AEW radar I believe I already posted this documentary before Interesting They really start from the scratch The lead designer does not know the principle of pusle doppler He has to first learn it It take him 10 years jsut to learn the basic
    Then they tought they get help from Israeli but the patnership was canned and they have to rely on themselves. But a lot of people doubted if China can independently developed the radar without outside help .Eventually they triumphed. The hero is freshly minted Phd name Zhang Liang

    Another documentary of SAR radar development And how they found the lost helicopter in Wenchuan earthquake using SAR radar. Interesting


    High resolution SAR picture

    All stealth airplane designed for X band low detect-ability.
    X band has a wavelength of centimetre, and it is usable only for active or semi active missile homing.

    To have low detectability in this band they need to decrease as low as possible the number of edges on the airplane, and cover them with RAM in comparable thickness \to the wavelength. All other surface will be dominated by geometric scattering.

    So, the S band has a wavelength of 10 cm, and the VHF is meter , means the RAM is useless, the airplane can be considered as a big edge, with smaller (S band) or no (VHF) geometric scattering .

    Means the effective radar cross section of an f-22 , even if the x band is as big as a square cm (require extremely costly maintenance procedures) in VHF will be several square meter.

    Of course it just solve the detect-ability issue, the SAM missiles still not usable.
