摘要： 针对某宽带雷达数字接收机对带宽、动态、处理速度、多通道等指标的需求,设计了一种基于新型ADC器件AD9680的宽带高动态全数字雷达接收机验证平台。文中首先在搭建的平台上对AD9680进行全带宽模式和数字下变频模式的性能验证与结果分析,根据分析结果提出改善AD9680动态性能的方案;其次,对AD9680两个通道之间的同步性做了验证,并提出了一种针对双通道时间偏差的优化方法。各项结果表明,AD9680能满足某宽带雷达的应用需求。

Abstract: A verifiable platform of wideband high-dynamic full digital radar receiver based on the new ADC AD9680 was designed for demands of bandwidth,dynamic,processing speed and multichannel.First,results of performance and analysis were acquired in full-bandwidth mode and DDC mode on the platform of AD9680.Solutions of AD9680 to improve dynamic performance were proposed based on the results.Then,dual-channel synchronization of AD9680 was verified and a method of optimizing dual-channel time deviation was proposed.All test results in this article showed that AD9680 would meet the requirements of certain wideband radar.

Key words: AD9680;wideband radar digital receiver;JESD204B;digital down conversion;dual-channel synchronization
