| 摘 要： | 设计了一种用于一维弹道修正弹的中频数字接收子系统。系统接收射频前端的中频信号,借鉴软件无线电思想,以模拟前端芯片AFE8201与DSP为硬件平台,通过加载软件实现了中频信号的模数转换与数字下变频及基带信号的处理。介绍了系统实现方式及AFE8201的特点和各部分参数的详细配置,并由MATLAB仿真与地面试验验证了系统的可行性。

| Abstract: | A kind of digital intermediate frequency(IF) receiving subsystem is designed for one dimension ballistic correction. The system is built on universal hardware platform based on analog-front-end(AFE) chip AFE8201 and DSP,referring to software-defined radio(SDR).Functions such as analog-to-digital converting and digital down-converting of intermediate frequency signal and baseband signal processing,which is from radio frequency front end module,can be realized by loading certain program.The paper emphasizes on the characteristics and particular configuration of AFE8201,and the system's feasibility is testified by simulation and experiments. |
