The APG63(V)2 was the first fighter mounted AESA radar to enter service worldwide. The first American F15C unit to receive the new radars were stationed at Elmendorf in 2000. In parison, the first European AESA entered operational service in 2012 and the first Russian AESA equipped fighters (Mig35) will not enter service until 2016. The initial US technological lead in AESA technology is attributable to substantial investments made in the late stages of the Cold War.圖1：裝備F15C的APG63(V)2型雷達(dá)。APG63(V)2是世界范圍內(nèi)最先裝備戰(zhàn)斗機(jī)并投入使用的雷達(dá)。位于埃爾門多的美國F15C單位夫于2000年最先接收該新型雷達(dá)。相比較而言，歐洲最早列裝使用AESA雷達(dá)的時(shí)間是2012年，而俄羅斯的Mig35戰(zhàn)斗機(jī)于2016年前不會(huì)裝備AESA雷達(dá)。美國在AESA技術(shù)上的領(lǐng)導(dǎo)地位，完全得益于冷戰(zhàn)后期的巨額投資。Author39。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。 performance figures associated with domestically produced radars is even harder to verify. This article39。s intent was to pile a wide variety of information on expected future developments in Chinese actively scanned electronic array (AESA) radars. Furthermore, the current “Threat Analysis of Foreign Stealth Fighters: Part I Chengdu J20” is largely dated with respect to developments with the J20’s avionics suite and this article subsequently provides more uptodate information on the J20’s AESA.作者注：在J31航空電子設(shè)備研制過程中（在《國外隱身戰(zhàn)機(jī)威脅分析第二部分：沈飛J31》中將進(jìn)行說明），目前尚沒有多少足夠可信，或經(jīng)證實(shí)，以及非投機(jī)性的解放軍戰(zhàn)斗機(jī)雷達(dá)資料。一些基礎(chǔ)信息，例如裝備特定戰(zhàn)斗機(jī)的雷達(dá)系統(tǒng)的名稱或型號(hào)與其生產(chǎn)廠商有關(guān)；中國國產(chǎn)雷達(dá)的性能參數(shù)很難被證實(shí)。本文的主要目的在于收集匯總有關(guān)中國有源相控陣?yán)走_(dá)未來發(fā)展方向的廣泛大量信息。此外，當(dāng)前《國外隱身戰(zhàn)機(jī)威脅分析第一部分：成飛J20》中已經(jīng)對J20的航電系統(tǒng)的發(fā)展?fàn)顟B(tài)進(jìn)行了大量描述，本文隨后將提供有關(guān)J20有源相控陣?yán)走_(dá)發(fā)展的最新信息。AESA radars represent a significant increase in detection power, reliability, and electronic warfare capabilities when pared to older electronically scanned arrays (ESA) and mechanically scanned arrays (MSA). This article largely focus on more technical aspects of AESAs but the basics of AESAs are cogently detailed by Karlo Kopp in Active Electronically Steered Arrays A Maturing Technology.對比較早的電子掃描陣列（無源相控陣）雷達(dá)和機(jī)械掃描雷達(dá)，有源相控陣?yán)走_(dá)具有在探測性能、可靠性和電子戰(zhàn)方面均有大幅提升。本文主要關(guān)注AESA技術(shù)，但該技術(shù)的更詳細(xì)描述可參考Karlo Kopp的《有源相控陣列——一個(gè)成熟的技術(shù)》一文。Three main determinants dictate the maximum number of transmit receiver modules a fighter radar can acmodate: the volume of the aircraft’s nose, the technological maturity of the firm/country’s T/R module packaging technology, and the effectiveness of the radar39。s thermal management system(s). The volume of the nose is a fairly intuitive constraint, the larger an aircraft’s nose is, the larger the radar can be. For example, the F15C’s nose cone is able to acmodate the much larger 1,500 T/R element APG63V(3) radar vs. the F16C Block 60 with its paratively smaller nose cone and its 1,000 T/R element APG80 AESA. Packaging technology refers to how many individual T/R modules can be installed within the finite space usually acplished by reductions in size of the individual T/R modules. The more techno
