    proven layout

    relible if you look at chinas defence industry all of the weapons they produce are improve version of the previous if it works why change it??

    also the kj-2000 maybe be experimental in the future there may very welll be different layout

    posted a summary of it on the JF-17 thread. Anyhow, this is the actual interview with the "dean?" of China's radar development house?
    http://www.news.uestc.edu.cn/ReadNews.dll?S_NewsID=18391
    A lot of surprising details coming out, normally China doesn't reveal this much about its development.
    一身朴素的衣装,满头规整的银发,精神矍铄快言快语的中国工程院院士王小谟面对我校学术交流中心挤挤攘攘的听讲者,没有过多的客套,一步跨上讲台,开始分析起“雷达发展的趋势”。
      雷达,一个国家电子工业的标志
      身为我国雷达工程专家,王小谟院士非常明确地指出:雷达,这个于1935年诞生在英国的探测器,长期以来包括现在也一直是一个国家电子工业的标志。
      我国从1954年开始成功研制出了中程警戒雷达,历经数十年的艰辛努力,目前我国雷达研制已经涵盖了低空、超低空、高空、三座标、预警等种类齐全的雷达系统。而某型雷达获得2005年国家一等奖,则标志着我国地面雷达已经进入了国际先进行列。
      “我国总体水平滞后国际5到10年,部分与国际同步。”王院士寄望在座青年,“希望在座各位为我国雷达贡献力量,把这5到10年的差距缩小、消灭,与国际同步。”
      未来雷达发展趋势是什么?王院士自有答案。“雷达已经是一个情报链中的一环,是网络中的一个节点,雷达不再孤军作战。”王院士用了《三国演义》中的开篇语,“分久必合,合久必分,多功能雷达系统将是下一步的发展方向。”
      而随着能高温工作、具备高抗辐射、频率更高、功率更大、处理速度更快的第三代半导体的出现,雷达研制出现了“数字前移、结构开放”的趋势,“专门工艺减少,研究重点不断调整,修改和更新周期更加快速,”王院士总结道,“雷达像其它产品一样,会有更多参与者,更新换代加快,希望大家参与进来。”
      争口气,研制出了“我们自己的预警机”
      日前,国家正式向全世界公布了我国自主研制的预警飞机,由此结束了我国没有预警机的历史。但国产预警机研制的背后,是一段国人奋发图强的历史。
      曾经,我国派出专家组远赴以色列,准备购买某型飞机,“但那款飞机技术极为简单”,王院士回忆说,“以色列还不卖。”回国后,王院士下了定语,老外越不卖,我们越要做出来!
      当时某中央领导鼓励专家们,“我们一定要争口气,研制出来后请美国总统来看看我们自己的预警飞机。”
      “在与航空设计师无数次面红耳赤的争吵后”,中国人终于有了自己的预警机,“在目前是世界上最先进的预警机,这一点是当之无愧的。”
      更具有突破意义的是,我国雷达研制已经从仿制型科研向自主型科研转变,“自主创新是必须的。”王院士对这一点看得很重。
      隐形飞机不是万能的
      一段时间,人们从电影里看到隐形飞机驰骋在天空如入无人之境,雷达似乎对它无能为力,隐形飞机赚取了大把大把的赞誉,似乎成了无法克制的战争法宝。但王院士一语道出了它的真实面貌,“隐形飞机也有很多弱点。”
     “隐形飞机是雷达系统长期研究的对象之一,”王院士揭密说,“不要把隐身材料看得很神秘,比如典型的隐形飞机F117,它也有致命的弱点,最大的特点是镜面集中反射,反射很大,利用组网雷达就可在不同方位检测出来。还有,国外的寂寞哨兵雷达对隐身就看得很清楚。”
    “任何东西都是有很多弱点的,”王院士意味深长地说,“对付隐身目标,我们还是有一定把握的。”
      电子科大要综合学科优势,变成“电子强国”
      王院士对我校的学科实力是比较欣赏的,“电子科技大学是在电子系统非常全面的学校,有关各方面的力量较强,在争取成为‘211’大学时就因为具有相关综合力量而胜出。”
    “成电还应该加强在微波方面的研究,而不仅是在毫米波方面。”王院士建议,“搞微波是你们学校非常强的一方面,而且微波领域多,搞好了可以一枝独秀,况且整个电子行业非常需要这方面的人才。”
    “希望将现有优势学科综合结合,变成‘电子强国’。”王院士有着更高的期待。
      在接受记者采访时,王院士也对我校学子提出了殷切希望,“虽然学电子很辛苦,希望不断学习,不断努力,既然干了这一行,就要坚持努力下去,才能取得更好的成绩。”
      王小谟,上海人,中国工程院院士,雷达工程专家。
    他于1961年毕业于北京工业学院(现北京理工大学)无线电工程系雷达技术,历任电子部第三十八研究所总工程师、所长,中国电子工业总公司军工局局长,电子科学研究院常务副院长,1995年5月当选中国工程院院士。为第九届、第十届全国人民代表大会代表,现任中国电子科技集团公司科技委副主任,电子科学研究院学位评定委员会副主席等职务。
      几十年来,他一直在科研第一线从事雷达设计研制工作,他设计研制了多种具有国际先进水平的雷达,尤其在三坐标雷达和低空雷达方面卓有建树,为国家创造出较大的经济效益,为军事电子工业的发展做出了重大贡献。20世纪60 年代创造性提出脉内扫描方法,使雷达系统大大简化。20世纪 70年代担任JY- 8 雷达主设计师,研制成功我国第一部自动化引导雷达。20世纪80年代主持设计的JY-9雷达,具有较好的低空性能,在国外的演习和综合评分中名列前茅,获得了国内外多部订货,是国际上优秀低空雷达。他亲自主持的项目分别于1985年和1996年获国家科技进步一等奖,部科技进步特等奖2项、一等奖1项。

    Hello everyone, previously President Musharraf of Pakistan was interested in the Y-8J, that would be the AWACS with the big round nose, similar to the Israeli Phalcon AWACS. It uses a "Sky Master" radar with a range reportedly of 85km, 360 degree coverage. But I was thinking, today fighters can shoot BVR missiles from ranges of 70-75 km. So then shouldn't the Y-8J's radar system have a but more range to it? The Erieye has a coverage of 300km! Maybe I am not sure, but I believe the Sky master range is 85km. If the PAF decides to purchase the Y-8J to compliment the Erieyes, it'd be the first user to use this particular AWACS system. Thus, enabling the PAF to have more reliability in it own individual Air Force. I am glad the PLAAF is concentrating to make ELINT,Maritime patrol and AWACS versions of the Y-8 transport air craft. From recent news, I remeber reading something about the Y-9. Will this Transport air craft have these types of other platforms; for example like the AWACS version. If there is such a thing, the take off weight can hold more and allowing the dish/balance beam to be bigger. That'll bring the Y-9 more coverage.

    If the PLAAF decides to do this, it can rely on itself in the AWACS section and then would not need further help from the Russians. :china:

    Don't forget, this aircraft (Y-8) is supposedly going to be used for some type of electronic jamming in addition to the other missions listed. So yes, it looks to be very useful. I wouldn't doubt Pakistan shows a desire to bring this aircraft into their inventory. To answer your question about Y-9, I believe it's the transport version only. Y-8 will cover most of the other duties. Tphuang may be able to correct me here. I'm not sure if it will be configurable like Y-8, but then again, I don't see why not from an engineering standpoint. And again, isn't Y-9 airframe derived from Y-8 anyway? Or at least very similar?

    you are totally wrong here. Y-8J is an AEW used to detect sea objects. It's main job is to coordinate strikes for the DDGs and such. What Musharraf came to see is the mushrrom Y-8. Which is basically the mysterious third type of AWACS with pla. It basically put that KJ-2000 style phased array radar on top of a Y-8. Y-8F600 is pretty much the standard platform that China is using for all of its special mission duties. Y-9 is pretty much just Y-8F600, but using domestic components. So, it would pretty much serve similar purposes.

    Thanks for your correction here. I had no idea that Y-8 was split into these two categories. A naval support one and an airborne command AWACS. I understand now what you mean about Y-9 also.

    Hi Guys!

    Its good to see the PLAAF/PLA investing in platforms and systems that serve to enhance their overall combat capabilities. The development of AWACS/AEWACS of the KLJ2000 and Y8 series as well as ELINT, EW as well as other versions (command, communication, JSTARS etc.) show that the PLA high command now appreciates the role of 'force multipliers' in modern air warfare. (That conclusion may be of course inaccurate, perhaps the reason we are seeing a proliferation of so many platforms currently is simply that only recently has money become available and research programs borne fruit!).

    IMO this is one of the better ways for defense money to be spent. The limited funds available to a developing country like China mean that not all programs or projects can be funded. AWACS, ELINT and EW investment will ensure not only improved detection and characterization of threats, but also the possibility of their disruption and degradation (via EW). They also take advantage of China's rapidly developing electronics industry. Furthermore, the presence of these platforms greatly enhances the limited capabilities of China's large but mainly obsolescent fleet of combat aircraft.

    The use of indigenously manufactured platforms (like the Y7, Y8 and maybe Y9) is icing on the cake, as they are cheaper, have an existing production infrastructure, and can be readily modified in-house to suite the needs of the client, (greatly enhancing security and independance), all the while keeping money flowing to their manufacturers, allowing for future investment and improvement. All in all a big plus for the developement of a comprehensive defense industry.
