台风战机升级主动相控阵雷达的收益
Eurofighter Typhoon, which can accommodate a large diameter antenna and provide high prime power, would derive particular advantage from incorporation of AESA technology.
台风战机可以安装大口径天线并提供充足的发电功率，可以充分从整合主动相控阵雷达技术中获取优势（F-16、阵风，小口径还电量不够的说的就是你们）
The availability of AESA technology will confer many significant operational, performance, and Through Life Capability Management (TLCM) benefits [1, 2]. The instantaneous beam-pointing capability, when governed by energy management algorithms, enables spectacular performance to be achieved. This is particularly true in air combat scenarios where the AESA system can be operated as a number of independent "virtual" radar systems, allowing
dedicated tracking of individual targets while maintaining full search coverage.
主动相控阵雷达技术将带来显著的实战表现提升，并将优化全寿命周期能力管理。...（细节想看的自己谷歌翻译）
Minimisation of logistic support requirements and reduction of through-life costs are major drivers for upgrading to E-scan. These are facilitated by the inherent high reliability of AESA technology and the ability to introduce new functionality through software development alone.
降低后勤支持需求与全寿命成本的压缩是升级为电扫雷达的主要驱动力。这些因为主动相控阵技术的高可靠性与仅仅通过软件升级开发即可引入新的作战模块而变得更加容易。
