摘　　要：通过有源相控阵技术、低噪声接收部件、紧凑布局和高级模态开发 ,F - 2 2雷达系统实现了在性能、可靠性和低可探测性方面的大幅提升。本文基于载机综合航电系统概念 ,在分析APG - 77雷达系统硬软件体系结构的基础上 ,探讨了F - 2 2雷达在生存性、杀伤性、可靠性和保障性等方面的独特优势 ,讨论了有源相控阵技术在低雷达散射截面战斗机上应用的折衷考虑。Significant improvements in performance, reliability and low observability have been provided for the F-22 radar system through the development of active phased-array technique, low-noise receiver components, compact arrangement and high-level modes. In this paper, the evaluation of exclusive advantages of the APG-77 radar in survivability, lethality, reliability and supportability is given based on the analysis of the radar hardware and software architectures in terms of integrated avionics system. The trade-off study of the active phased-array technique application to low RCS fighter aircraft is discussed.
