摘　　要：联合式航空电子系统的集成式设计方法导致飞机成本及载荷瓶颈严重制约了新一代航空器整体性能的提高。因此必须改变传统设计模式,加强先进体系结构的顶层研究和系统设计,以增强空中信息优势。论述航空电子开放式体系结构的层次化特征,阐述未来网络化发展趋势,提出并分析一种适于机载综合CNI系统前端的并行多通道宽带中频带通采样结构,并通过功能单元定义、分类与综合,完成模块化系统设计。最后进行航空电子射频传感器之间结构综合的可行性分析。上述系统前端结构及设计方法对航空电子综合化具有重要意义。The subsystem-combination design of federated avionics system dramatically limits the promotion of the performance of next-generation aircrafts.As a result the traditional approach should be totally changed with the architecture of next-generation newly designed from the top level with standardization,which aims to enhance the aerospace information dominance.This paper presents the features of the open layered architecture for avionics,and deseribes the trend of net-centric in future.Firstly,a system front-end structure of broadband IF is proposed and analyzed for the airborne CNI integrated system.Secondly,the system-level design of modular structure within the CNI system front-end is achieved through the definition,classification and integration of functional units.Finally,the feasibility of integration across different avionics RF systems is discussed.
