CBB架构宽带通信雷达一体超外差接收机研究与设计

Research and design of wideband communication radar integrated superheterodynereceiver based on CBB architecture

研究设计基于CBB(Common Building Block)架构的宽带通信雷达一体超外差接收机,旨在提供一种快速、高效的多用途接收整机设计方法。该方法设计7种共用基础模块,各自实现接收整机中的一部分技术与功能指标;对7种共用基础模块按照各自特点进行系列化研制、生产,形成各自的产品库;在通信雷达一体超外差接收机的设计中,结合技术指标要求,选用相应的共用基础模块进行组合,即可完成相应的整机设计工作。此方法的优点是:简化整机设计难度、减少重复开发、缩短研制周期、提高产品成熟度,以及便于设备的测试、维修等。

A new research and design method based on CBB for integrated wideband communication radar superheterodyne receivers is proposed in this paper,aiming to provide a fast and efficient design method for multi-purpose receiver design.Seven common basic blocks have been established in the proposed method.Each block is responsible for part of the functions of a receiver.Respective product libraries for the seven common basic blocks have been built through serial development and production based on their respective characteristics.During a superheterodyne receiver design,we can just select several proper CBB from the library according to the technical requirements and combine them to complete the corresponding receiver.This can simplify system engineering,reduce repetitive development,shorten the development cycle,improve product maturity and facilitate testing and maintenance of the equipment.
