摘　　要：提出了一种高分辨率雷达图像采集系统的实现方法,着重讲述了雷达信号的采集,大容量图像数据的传输控制、预处理、数据的缓存,以及通过PCI接口与PC机的通讯。系统中采用高速A/D采样芯片和FPGA,满足了高分辨率采样的要求,提高了系统的稳定性,简化了电路的复杂性,缩短了设计周期,并有效控制了成本。The paper presented a method to collect high resolution of radar image, and it emphasized on the collection of radar signal, the transmission of huge image data, the prep rocessing, the data remissive storage and the communication to PC by PCI port. The sys- tem used high speed AD sampling IC and FPGA technology. It satisfied the requirement of high resolution sampling, improved the stability of the system, simplified the circuit, shortened the design cycle and controlled the cost effectively.
