摘要: 該文給出了一種高分辨率合成孔徑雷達(dá)實(shí)時(shí)數(shù)據(jù)處理系統(tǒng)的方案設(shè)計(jì)與實(shí)現(xiàn)。該方案采用PowerPC G4處理器進(jìn)行運(yùn)算，采用VME作為系統(tǒng)總線(xiàn)，RACE++作為高速數(shù)據(jù)通道，具有穩(wěn)定、計(jì)算能力強(qiáng)、可靈活配置等優(yōu)點(diǎn)。通過(guò)簡(jiǎn)單的擴(kuò)展或裁減就可以提供不同的計(jì)算能力與數(shù)據(jù)帶寬，可以適合于多種分辨率與模式的SAR系統(tǒng)實(shí)時(shí)數(shù)據(jù)處理。Abstract: Design and realization of a real-time high-resolution SAR data processing system is proposed. By the adoption of PowerPC G4 as DSP, VME as system bus and RACE++ as high speed data exchange path, this stable system has great performance and flexible expansibility. To fit different requirement of real-time SAR data processing system, variable performance can be achieved by simply extension.
