主动电子扫描阵列（AESA）自20世纪60年代以来已成功应用于机载雷达，显著提升雷达性能。AESA通过独立配置的T/R模块实现多频束操作，增强抗干扰能力并提高通信安全性。同时，其模块化设计增加可靠性，故障不会导致整个系统的功能丧失。AESA雷达在降低馈线损耗、实现多功能同步以及适应性波束形成方面具有重大突破，成为现代战机的重要技术。

Introduction

Since the 1960s, after more than 40 years of efforts, Active Electronically Scanned Array (AESA), often referred to as active phased array technology, has finally achieved successful applications on airborne radar.

International Online Report: A proposal by the US Defense Department's National Defense Science Committee's recommendations for the development of US military aircraft radars emphasizes that active phased array technology can greatly expand the capabilities of radars and improve radar performance. The radar of the fighter radar, early warning and surveillance aircraft should be the AESA system. In fact, in addition to the new generation of fighters such as the F-22 and F-35 equipped with AESA radars without exception, the US AESA improvements to third-generation active fighters, bombers, early warning and surveillance aircraft have been planned and The corresponding financial support. A common view in the industry is that from now on, there will be no place for manufacturers who do not master the manufacturing capabilities of AESA radar. In addition to the United States, Western countries such as Russia, France, Germany, the Netherlands, Sweden, the United Kingdom, and Israel are also engaged in extensive cooperative development and substantial capital investment in this technology field.
