摘要
该文介绍了合成孔径雷达实时成像处理器转置存储器的基本工作原理,讨论了转置存储器的两种主要结构:三页式结构和两页式结构,并指出了这两种结构各自的优缺点。重点介绍了两页式转置存储器结构的典型应用,给出了以双数据率同步动态内存(DDRSDRAM)作为主存储器构成的两页式转置存储器的电路结构和实现结果。
The Corner Turn Memory(CTM) for real time imaging of the Synthetic Aperture Radar(SAR)is presented in this paper. Two types of structure of CTM: the three-frame and the two-frame are discussed, of which the merits and flaws are compared. The representative application of the two-frame CTM is introduced predominantly, of which the implementation in circuit and the result are given with the Double Data Rate Synchronous Dynamic RAM(DDR SDRAM)served as the main memory.
