Abstract

Digital RF memory(DRFM),based on high-speed sampling and digital storage technology,has the function of RF signal storage and reproduction.It is used widely in the radar echo signal generator.This paper introduces the principle,structure,performance indicators of DRFM,and analyzes the factors affecting its performance.The application of DRFM in a specific target simulator is discussed.Finally,some issues which should be paid attention to during the design phase are given.
