摘要: 該文介紹了合成孔徑雷達(dá)實(shí)時(shí)成像處理器轉(zhuǎn)置存儲(chǔ)器的基本工作原理,討論了轉(zhuǎn)置存儲(chǔ)器的兩種主要結(jié)構(gòu):三頁(yè)式結(jié)構(gòu)和兩頁(yè)式結(jié)構(gòu),并指出了這兩種結(jié)構(gòu)各自的優(yōu)缺點(diǎn)。重點(diǎn)介紹了兩頁(yè)式轉(zhuǎn)置存儲(chǔ)器結(jié)構(gòu)的典型應(yīng)用,給出了以雙數(shù)據(jù)率同步動(dòng)態(tài)內(nèi)存(DDR SDRAM)作為主存儲(chǔ)器構(gòu)成的兩頁(yè)式轉(zhuǎn)置存儲(chǔ)器的電路結(jié)構(gòu)和實(shí)現(xiàn)結(jié)果。Abstract: 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.
