基于多FPGA的SAR成像信号处理机设计

Design of SAR Imaging Signal Processor Based on Multi-FPGA

文中针对FPGA在数字信号处理领域中一些区别于DSP的优点,以及SAR信号仿真与处理的大运算量、高数据通信量和实时性对成像处理机的可靠性和稳定性等特点,设计开发了一种基于多FPGA的SAR成像信号处理机。详细介绍了系统结构、数据通信方式以及FPGA配置等关键问题。

FPGA is superior to DSP in some digital signal processing systems. The larger data traffic and the higher processing ability are required in the development of SAR real-time imaging technology. At the same time, the signal processing must have better reliability and stability. This paper tells of a multi-FPGA-based SAR imaging signal processing system. The key points of the system architecture, data communication mode and FPGA configuration are all described in detail.
