摘　　要：为了提高数字射频存储器(DRFM)的存取速度、存储深度和系统的灵活性,采用了模块化设计原则。以PXIE机箱为平台,运用固态存储技术实现信号的高速存取,完成了包括上、下变频模块、中频信号采集模块、中频信号还原模块、固态存储模块以及处理控制核心等电路的设计。重点研究固态存储技术和PXIE技术在DRFM中的应用,为进一步提高DRFM的性能提供了参考。Using the principle of modular design and taking a platform of PXIE to improve reading and writing speed,storage depth and flexibility of DRFM.High-speed reading and writing of the signals are achieved by solid-state memory techniques,the upper and lower frequency conversion modules,intermediate frequency signal collecting modules,intermediate frequency signal restore modules,memory modules and processing core are also designed.The application of solid-state memory and PXIE techniques in DRFM are studied as a main part,which provides some references for further improvement of DRFM.
