improve seeker for KH-31P

美媒:中国为KH-31反辐射导弹换装国产引导头

美国环球战略网11月12日对中国最近做出的对世纪80年代引进的俄制的Kh -31P更换更新国产引导头的事宜做了评论。认为中国设计制造的新的反辐射雷达引导头比俄罗斯原装货精度更高。但显然中国更希望获得美国AGM-88的技术并整合到Kh-31P上去。

东方网11月17日报道 美国环球战略网11月12日刊登了名为《中国正寻求强有力的反雷达导弹》的文章。它对中国最近做出的对世纪80年代引进的俄制的Kh -31P更换更新国产引导头的事宜做了评论。文章认为中国设计制造的新的反辐射雷达引导头比俄罗斯原装货寻的频率范围更广,精度也更高。但对于美国更先进的AGM-88D/E,中国显然更希望获得其技术并整合到Kh-31P上去。
文章称,最近有来自中国的消息透露,其现已升级了200枚于20世纪80年代引进的俄制的Kh-31P反雷达导弹(ARM)。因为中国在引进改武器后,对这种俄制导弹的(检测雷达辐射波并引导导弹飞向雷达目标的)引导头并不满意,于是开始自行研制。中国产的新引导头能发现更广的雷达频率范围,达2至18赫兹(GHz);精度更高,误差半径在8至10米以内。
Kh-31最初是被用作机载的反舰导弹。但俄罗斯人很快意识到,如果换用另一种引导头,该导也能变成出色地的反雷达武器。反舰版本的Kh-31航程半径50公里,而反雷达版本的Kh-31有效航程则达110公里。这种600千克重的导弹携带有一个87公斤重(约191磅)重型弹头。
美国制造的与之匹敌的导弹是36吨重的AGM-88。其最新研发的型号为AGM-88E。首批量产的“E”型是在历经了数十年来研发努力之后推出的,最早将于明年交付使用。在过去的27年里,所有型号的AGM-88导弹加起来总共生产了超过23000枚。
该导弹目前在役最先进型号为AGM-88D,使用全球定位系统,飞行员可以命令导弹朝发出雷达波的信号目标发射,也可用于攻击单独地面目标点。AGM-88导弹飞行速度很快,达1.9马赫,攻击距离超过100公里。每枚AGM-88D的导弹造价将近10万美元。但反辐射标准版的AGM-88就更昂贵,由于其使用更复杂的传感器,可以检测并引导导弹飞向更多种类的雷达信号源目标,所以这种型号的导弹每枚造价约30万美元。其在机载或高速飞行中就开起GPS,当反雷达导弹引导头找到发出辐射源的雷达目标后,迅速将数据存储于GPS定位系统之中,不管在飞行途中目标雷达是否关闭,导弹也会根据事先设置的数据自动飞向目标。
新版AGM-88E导弹,则使用一种更昂贵的方式,使制导导弹高速直接飞向敌方开启的雷达,并在末段迅速关闭动力系统,以免遭到对方红外寻的导弹的拦截。这种导弹,也称为高级反雷达制导导弹(AARGM),是由美国和意大利公司联合研制的。最早型号的AGM-88早在20世纪80年代就已开始服役。由于技术的不断进步,早期20世纪60年代开始装备的反雷达导弹(ARM)也迅速演变成如今的高速反雷达导弹(HARM)。
AGM-88E能记忆雷达开启时所在的位置,并能开启以自有的高解析度毫米波雷达,来精准飞向的雷达波目标。最后,AGM-88E将传回一张目标雷达被击毁之前的图片。所以,控制导弹的操作人员可以通过这些图象确认被攻击目标的样子,并最终决定是否攻击。目前,来自美国海军及海军陆战队、意大利和德国的军队已下达定单,定制该导弹的订单实数已经超过2000枚。
在文章最后,作者认为中国显然很希望获得美国这种高级的ARM技术,并将其整合到其Kh-31P中去。

Re: improve seeker for KH-31P

A simple summary of the passage.

"The author is referencing to US media on the seeker that China had build for their KH-31P missile. This imporved seeker is said to be much more accurate than the Russian's one and was able to detect a wider range of radar frequency (2 to 18GHz). Although more accurate and (i believe) generally offer a better performance than the Russia build one, it is still inferior to the US made AGM-88 missiles. And that China is very interested in acquiring the AGM-88 seeker's technology to be integrated to their Kh-31P missile. all the other are a comparison of the US build AGM-88 and its variants."

I believe China is on the right track... although she didn't have the accuracy of the US build system now, but I believe that as soon as their Beidou system is fully functional, the accuracy of their missiles will naturally improved. And by now, it seemed that China's seeker technology is closing in on the Russia, or may have already surpass the Russian's.

Re: improve seeker for KH-31P

wow why does globalstrategy have to mention that China "wants" AGM-88...its like saying China is developing 4th gen but really wants F-22 lol.

but is this article talkin about YJ-91? 10m CEP prolly isnt good enough, and against Taiwan's air defence, the 110km range needs improvement too. i say 5m CEP and 150 km would be good numbers.

oops its called strategy page, mixed it up with globalsecurity lol

Global strategic page is not reliable sit, why some one still post the whole article like that?

Actually if you look at US AGM-88. Their accuracy was achieved alot by GPS system that was already fully functional. The chinese in order to achieve that type of accuracy would required the GPS system. In any military action against Taiwan, I believe that the GPS will be denied to the Chinese. Thus I think the main bottleneck still lies with the Beidou system that was still not fully and completely functional.

Another way of bypassing the Beidou system in Taiwan scenario was to develope better target acquirisition and controlling system in the form of UAV or command aircraft that will need to be above or near Taiwan's airspace to provide data link and transfer and guiding the missile down more accurately.

I don't trust the article too. But we couldn't say that China didn't want the AGM-88 technology too. It is just that at this present time, US will definitely not sell the technology or any military technology to China. So they have no choice but to develope their own. If one day, China is able to get advance western technology and weapon system, I believe it will be a great blow to their homegrown weapon system industry.

Using that logic... if (that is a IF), US allow sales of any amount of F-22 to China, I believe the Chinese would jump at that deal and their own 4th gen aircraft development will either stop or be seriously hampered.

Yes, agree ... weapon embargo to China from US and EU is actually a good thing for Chinese, as it forces them to develop their own ones .... with any means ..... even "steal" it .... it doesn't matter ... the only matter is whether you have it or not

is the original article on strategypage.com, I don't understand why Chinese media are so keen on quoting from that site, is there a collective bullshit detector malfunction in China or something?

Re: improve seeker for KH-31P

actually the technology is within reach of Chinese engineer,during the zhuhai airshow,NORINCO display combine laser guide/GPS bomb.other was mention was combine semi active laser guided/millimeter wave seeker for 155mm guide round..
this fused sensor,mean the ground designator do not have to maintane there lasing, until the impact,from the moment laser seeker pick up or received the "reflection".the ground designator can move away from firing zone.

I'm guessing they are liable to believe an article as long as it puts China in a positive light...in this case the claim that China is ahead of Russia...
Just like many Americans would scorn any article putting China at post-1980s technology ;)
