阐述目前数字相控阵雷达下行数据采集接收的系统设计应用场景中,单板多通道同步采集、多板卡同步采集的设计需求越来越多.为此,以ADI的双通道14位模数转换器AD9680芯片为基础,利用JESD204B协议具有传输速率高、抗干扰能力强、易于测试确定性延迟实现多片间同步的特性,通过对关键信号的设计和处理,介绍一种多通道间和多板卡间的数据同步采集实现技术,从而解决数字相控阵雷达下行数据的相位一致性问题.该技术具有良好的可扩展性,可满足实际工程的需求.
Design on a Method of Synchronous Acquisition for Multi Board Cards
This paper describes the design and application scenarios of digital phased array radar downlink data acquisition and reception systems,which are more and more requirements for the design of single board multi-channel synchronous acquisition and multi board cards synchronous acquisition.This article is based on the dual channel 14bit analog-to-digital converter AD9680 chip of ADI,and utilizes the JESD204B protocol to achieve inter chip synchronization with high transmission rate,strong anti-interference ability,and easy testing of deterministic delay.Through the design and processing of key signals,a data synchronization acquisition technology based on the JESD204B protocol for single board multi-channel and multi board cards is introduced,Solved the phase consistency problem of digital phased array radar downlink data.This technology has good scalability and can meet the needs of actual projects.
