摘要
随着高速ADC器件和高性能通用处理器的发展,雷达的数字化程度越来越高。分析了数字阵列雷达的优点;介绍了现有的典型数字阵列雷达系统,总结了数字阵列雷达的典型结构;介绍了高速ADC器件、高速采集板、正交解调和通道均衡等关键技术的发展现状。随着相关技术的不断进步,阵列雷达必然向着数字化、软件化和多功能的方向发展。
With the development of high speed ADC and general processor with high performance,the digitalization degree of radar has reached a level much higher than before.Firstly,this paper analyzed the advantages of Digital Array Radar（DAR）.Secondly,it introduced several typical DAR systems and summarized the typical architecture of DAR.Finally it introduced the development of RF direct sampling all-digital receiver,all-digital quadrature demodulation,wideband channel equalization,and the wideband signal digital beamforming technology.With the development of relevant technology,the array radar will surely develop to be digital,software defined and multifunctional.
