-
摘要: 该文给出了一种高分辨率合成孔径雷达实时数据处理系统的方案设计与实现。该方案采用PowerPC G4处理器进行运算，采用VME作为系统总线，RACE++作为高速数据通道，具有稳定、计算能力强、可灵活配置等优点。通过简单的扩展或裁减就可以提供不同的计算能力与数据带宽，可以适合于多种分辨率与模式的SAR系统实时数据处理。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.
