Chinese Airborne Radars

F2 do you have any more chinese book want to search ? I can help you with it.
 
Also, i visited Paralay's forum and found this. Apparently this is the AESA antenna intended for J-16.

Going with Deino's post in previous page, for 1760 TRM count, Using Irbis-E size (90 cm, 0.63 sqm area) Showed element area of about 0.000357 sqm. Based on the arrangement of the array, it appears to use triangular lattice. Using the relationship of the element spacing (Anyone interested can read the deriviation in Chapter 13 of "Radar Handbook 3rd Edition" and assumption of full 120 degrees scanning. The frequency of the radar could be estimated to be 9136 MHz. If the antenna is Bars sized with 0.78 sqm. The frequency would be 8211 MHz.

Thank you! That series has a book a the J-10 and it’s creator. If you see it would you let me know? It might have useful stuff.
Of course , I will try to find it when I over the busy work this week.

Good news, I found it and I will upload it tomorrow. :)
 
Removed some posts. Please don't upload or link to entire copies of published books in the forum.

Oh! Thanks! ... but do you also know the designations of the PESA in the J-10B, the AESA used by the J-11BG and J-10C and most of all, I heard reports, the latest batch J-10S (or AS) refitted with WS-10B engines would already use an AESA too! Do you know here more too?
 
A 250km detection range against a 0.1 m2 target? That means 400km against a 1m2 target roughly.

Hard to believe.

Yeah... i suspect it's from different paper on ground based radars as it mention Height. Not a problem for airborne radar but ground based one.
I found a copy of the full paper

Nice work. Guess those are for general AESA designs. not really specific on any fighters.
Yea I do no think they are for a particular fighter but I have seen the smaller one associated with the J-10B radar. I wonder if it’s the same technology, like a demonstrator.
 

Some footage I haven’t seen. Seems like a 14 institute radar history from J-8 but I can’t read Chinese.
 
Moreover, on Page 91, 全球防衛雜誌 Defence International 2007 April 272 reads:
“就雷達模式而言,Type 1473/KLJ-3目前應已具備完整的空對空能力,如單目標追蹤(STT)、掃瞄帶測距(RWS)、空中 近戰次模式/ACM Mode(HUD. Vertical scan, boresight, wide-angle acquisition. Stewing)、掃瞄帶追蹤(TWS)、速度搜索(Velocity search)、機群解析(raid assessment).空對地测距(AGR):至於空對面雷達模式包括都卜勒敏銳波(DBS)、真實波地面測繪(RBGM)、地面活動目標顯示(GMTI)、地面活動目標追蹤(GMTT),地形(TA)、固定目標追蹤(FTT)、地形追蹤(TF)、海面目標搜尋(SS).則可能僅完成部 份模式的驗證,多半的功能應在
發展或驗證中”
Which roughly translates to:
"As far as radar mode is concerned, Type 1473/KLJ-3 should currently have complete air-to-air capabilities, such as single target tracking (STT), scanning band ranging (RWS), air close combat sub-mode/ACM Mode (HUD, Vertical scan, boresight, wide-angle acquisition, Slewing), scanning band tracking (TWS), velocity search (Velocity search), fleet analysis (raid assessment), air-to-ground ranging (AGR): As for the air-to-ground radar mode Including Doppler sensitivity wave (DBS), real wave ground mapping (RBGM), ground moving target display (GMTI), ground moving target tracking (GMTT). terrain avoidance (TA), fixed target tracking (FTT). terrain tracking (TF) and Sea Target Search (SS), it is possible that only part of the model verification has been completed. Most of the functions should be under development or verification."

J-10A radar (1473), I would like to track down a copy of the primary source “ 全球防衛雜誌 Defence International 2007 April 272”

 

Presumably 1491/1493

It is 1492, the model of the antenna ends with 92B.
1493 was only used on the J-11B, this specific model of J-8 is the J-8DF which is using 1492.

The author of that post was nice enough to give me the article

Here is the page in question

Thanks to the leap forward in information technology in the 1990s, it is speculated that the Type 1473/KLJ-3 currently installed on the J-10A has the latest technology level of traditional Doppler pulse radar, and its average power, maximum detection range, target tracking capability, pulse width, beam width, signal processing, sidelobes blanking & cancellation, anti-interference and waveform PRF interleafing capabilities are better than those of the Type 4.
Radars based on technology from the 1970s and 1980s are commonly used on modern fighter jets.

In terms of radar modes, the Type 1473/KLJ-3 should now have complete air-to-air capabilities, such as single target tracking (STT), scanning band ranging (RWS), air close combat sub-mode/ACM Mode (HUD, Vertical scan, boresight, wide-angle acquisition, Slewing), scanning band tracking (TWS), velocity search, raid assessment, air-to-ground ranging (AGR); As for air-to-surface radar modes, they include Doppler sensitive wave (DBS), true wave ground mapping (RBGM), ground moving target indication (GMTI), ground moving target tracking (GMT), and ground moving target tracking (GMT). (GMTT), terrain avoidance (TA), fixed target tracking (FTT), terrain tracking (TF), surface target search (SS), it is possible that only part of the mode verification has been completed, and most of the functions should be under development or verification, first meeting the needs of the main mission of air superiority operations, and then gradually expanding the air-to-surface mode, and finally achieving the full function of the radar (most Western radars also adopt this method)
Some reports indicate that the Type 1473/KLJ-3 has a maximum range of about 120~150km, can track 24 targets simultaneously and engage 6 targets simultaneously. Referring to the performance of the new Russian-made X-Band (8~12GHz) conventional Doppler pulse radar, such as the Kopyo-M Zhuk-MSE series, the average power is about 1.5KW, the maximum detection distance for an air target with an RCS of 5m2 is 85 and 180km respectively (40 and 80km for tail pursuit), and the target tracking and engagement capabilities are 10 (tracking)/4 (engagement) and 20/4 respectively. It can be judged that the radar of the J-10A should be better than the Kopyo-M and slightly inferior to the Zhuk-MSE-
