| 摘要: |
| 针对机载通信导航识别（Communication,Navigation and Identification，CNI）系统对轻小型地面保障设备提出的更高要求，在分析CNI系统信号特征对地面保障设备硬件平台需求的基础上，通过对比超外差、射频低通采样和射频带通采样等架构的特点，搭建了一种全新的基于软件无线电的综合检测设备通用平台架构，并给出了硬件平台总体设计和主要模块设计，同时分析了CNI检测部分功能信号的实现。实际工程应用证明，在配置同样检测功能的情况下，该设备在重量、体积、功耗等方面的优势明显，可为其他检测设备设计提供借鉴。 |

| Abstract: |
| According to the higher requirements of airborne communication,navigation and identification(CNI) system for small and light ground support equipment,the requirements of CNI system signal characteristics for ground support equipment hardware platform are analyzed.By comparing the characteristics of superheterodyne,radio frequency(RF) low-pass sampling and RF band-pass sampling,a new general platform architecture of comprehensive detection equipment based on software defined radio(SDR) is built,and the overall design of hardware platform and main module design are given.At the same time,the realization of some functional signals of CNI detection is analyzed.The practical engineering application shows that the equipment has obvious advantages in weight,size,power consumption and so on under the same detection function,which can provide reference for other detection equipment design. |
