摘　　要：动目标显示是现代雷达重要的频域信号处理措施。本文在FPGA信号处理平台上,用QDR SRAM作为雷达多周期数据存储器件,实现了动目标处理功能。该系统可以可靠地实现对QDR SRAM的读写控制,实时地完成动目标对消等信号处理功能,在实际工程中得到了应用。The Moving Target Indication （MTI） is an important measure in the frequency-domain signal processing for modem radars. The MTI processing is implemented with QDR SRAM as the muhicycle data memory on the FPGA signal processor. The test results show that the R/W control of QDR SRAM can be made reliably, and the signal processing such as the MTI cancellation can be accomplished real-timely with engineering applications.
