- 介绍一种基于FPGA、多通道DA/AD的阵列信号收发处理硬件结构,是目前相控阵阵列信号生成、数字波束处理的常用技术手段。与现有中频相参多级变频调制/解调技术相比,该方案采用集成式芯片AD9371,通过内置混频器及DDS技术直接产生射频信号,可减小TR组件体积,提高系统集成度,对多通道TR组件通道的工程设计有一定参考价值。
- Abstract:
- This article introduces a hardware structure of array signal receiving and sending processing based on FPGA and multi-channel DA/AD, which is a common technical means for array signal generation and digital beam processing in phased array radar. Compared with the existing IF coherent multi-level frequency conversion modulation/demodulation technology, this solution uses the integrated chip AD9371 to directly generate radio frequency signals through the built-in mixer and DDS technology, which can reduce the volume of TR components and improve system integration. It has certain reference value for the engineering design of multi-channel TR component channel.
