中國有源相控陣技術發(fā)展狀況及其戰(zhàn)略影響(存儲版)
【正文】 Research Institute of Electronics Technology (NRIET) or the China Leihua Electronic Technology Research Institute (607 Institute) was able to develop sufficient packaging technology that would enable 1,856 T/R modules within the J2039。The J16 utilizes the Su27BS airframe which has room for a meter aperture in the nose which is on par with the F15 and F22 in terms of volume (Kopp, 2012). The 1,500 element N036 Tikhomirov NIIP AESA has a similar aperture size to the electronically scanned array (ESA) IrbisE radar featured in the Su35 series of fighters which shares the base Su27 airframe. If the 1,760 T/R figure is correct it would indicate the Chinese aerospace industry has eclipsed Russian T/R module packaging technology as the N036 is arguably the most advanced Russian fighter mounted AESA. Similarly, the most advanced US fighter mounted AESAs such as the APG77(V)2 and APG82(V)1 contain 1,500 T/R modules*. While the prospect of Chinese avionics firms reaching parity with US and Russian firms is more plausible within two generations of designs, the author is skeptical the 1,760 figure is correct given the unsubstantiated nature of the image and the fairly substantial 260 T/R discrepancy between the J16 radar figure pared to the most advanced US and Russian AESA designs. Therefore, the author speculates it would be more reasonable to assume a figure between 1,200 and 1,500 TR modules for the J16 rather than the 1,760 figure.J16采用了Su27BS機身設計，從容量方面看，與F15和F22相同（Kopp，2012）。以色列的ELM2052 AESA雷達，在F16和FA50戰(zhàn)斗機上都擁有一定市場（后者是韓國聯(lián)合航空工業(yè)集團在洛克希德馬丁公司F16上研發(fā)的一款戰(zhàn)機），據(jù)估計，該型雷達擁有約512個T/R組件（Trimble公司，2014）。 J10B units achieved initial operational capability (IOC) in October of 2014. The volume of the J10s nose cone is not substantially different from that of the F16 or the Israeli Lavi from which the J10 is partially based. Therefore, if one were to assume China had reached parity with the United States in packaging technology, the 1,200 T/R module figure would be plausible but slightly high. For parison, the APG80 AESA for the F16C/D Block 60 has 1,000 T/R modules (DSB, 2001). However, it is unlikely that China has been able to reach parity with the United States in terms of packaging technology on their first generation AESA design. Neither Russia nor Israel was able to field 1,000 T/R element arrays within their first generation fighter mounted AESAs for similar nose volumes as the F16 with the Mig35 and Israeli F16 respectively.中國軍事防御論壇上登載了圖片的副本，圖片聲稱J20的AESA系統(tǒng)T/R組件數(shù)量為1856個，J16為1760個，J10B為1200個。在眾多已裝備的航電機載設備中所使用的傳統(tǒng)風冷技術，并不適用于高密度封裝的AESA系統(tǒng)，因此，現(xiàn)代AESA系統(tǒng)采用液冷技術。因此，在封裝技術上的進步，將允許工程師們在固定的飛機鼻錐空間里布置更多的T/R組件。本文主要關注AESA技術，但該技術的更詳細描述可參考Karlo Kopp的《有源相控陣列——一個成熟的技術》一文。s Note: During the research process on the J31’s avionics (for the uping Threat Analysis of Foreign Stealth Fighters:J31 Part II), it became apparent that very few credible, verifiable, and nonspeculative English based source materials existed on the subject of PLA fighter radars. Basic information, such the proper name or designation of a radar system is utilized by a particular fighter often varies between sources。The Technological Maturity of Chinese AESA Technology amp。Author39。AESA radars represent a significant increase in detection power, reliability, and electronic warfare capabilities when pared to older el
