【正文】 ps to drive the coolant through channels in the antenna, and then route it to a heat exchanger. That might be an air cooled core (radiator style) or an immersed heat exchanger in a fuel tank with a second liquid cooling loop to dump heat from the fuel tank. In parison with a conventional air cooled fighter radar, the AESA will be more reliable but will require more electrical power and more cooling, and typically can produce much higher transmit power if needed for greater target detection range performance (increasing transmitted power has the drawback of increasing the footprint over which a hostile ESM or RWR can detect the radar” – Kopp, 2014“由于微波發(fā)射放大器的特性，T/R組件中發(fā)射部分的用電效率典型值小于45%。通過減小單個T/R組件的體積，封裝技術決定了再固定的空間內可容納的最大T/R組件數(shù)量。此外，當前《國外隱身戰(zhàn)機威脅分析第一部分：成飛J20》中已經(jīng)對J20的航電系統(tǒng)的發(fā)展狀態(tài)進行了大量描述，本文隨后將提供有關J20有源相控陣雷達發(fā)展的最新信息。美國在AESA技術上的領導地位，完全得益于冷戰(zhàn)后期的巨額投資。 Strategic Impacts中國有源相控陣技術發(fā)展狀況及其戰(zhàn)略影響Image 1: APG63(V)2 radar installed on an F15C. 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. performance figures associated with domestically produced radars is even harder to verify. This article39。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。Image 2: US early production quad packed transmit receiver modules. The United States no longer produces quad channel T/R modules and has since produced single T/R module designs. Less advanced AESAs such as the ZhukAE utilize multiT/R channel designs, it is possible China39。美國設計研發(fā)的聚α烯烴（PAO）冷卻液是一種合成液壓液。J10B飛機可能是首款使用AESA系統(tǒng)的中國國產(chǎn)戰(zhàn)斗機；J10B單位在2014年10月形成初步作戰(zhàn)能力（IOC）。除美國本土公司外，只有法國航空業(yè)Thales公司在第一代AESA雷達（RB2E）上使用超過1000個T/R組件（Avionics Today雜志，2009）。提赫米洛夫儀器制造研究院制造的N036 AESA雷達系統(tǒng)擁有1500個T/R組件，與電子掃描陣列（ESA）IrbisE雷達（無源相控陣PESA）孔徑尺寸相似，后者在與Su27機身結構設計相仿的Su35上使用。s nose, the density of the T/R modules would create significant cooling problems. For example, Phazotron39。Many discussions with respect to the relative stealthiness of fighter aircraft are limited to merely paring radar cross section estimates while entirely neglecting alternate means of detecting aircraft such as RWRs or other emission locator systems. David Axe succinctly pares the process of how RWRs function to how a flash light carried by another person is easily visible in a dark room. AESAs emit a substantial amount of energy, especially designs with a greater number of T/R modules, which enables passive emission locator systems to detect an AESA. The addition of an LPI software for AESAs mitigates the risk of RWR detection.許多有關戰(zhàn)斗機“相對隱身性”的討論，只限于比較雷達截面積評估，而完全忽視了其他對空偵察手段，例如：雷達告警接收機（RWR）和其他輻射定位系統(tǒng)。 and when they are close enough to be engaged or avoided, they are continuously tracked Bill Sweetman, 2001“通過對雷達信號的輻射功率、持續(xù)時間和輻射空間管理，保持飛行員對戰(zhàn)場態(tài)勢的有效感知，并最大限度降低信號被偵測的機率。 USAF, 200
