摘　　要：近年来FPGA(现场可编程门阵列)已成为高性能数字信号处理系统中的关键部件。介绍了以FPGA为核心控制和处理芯片的导航雷达接口板,实现对雷达方位、触发和视频信号的预处理。利用FPGA上的NIOS软核与显控计算的串口通信,显控计算机实现对该系统的控制及状态监控,而叙述了抗同频异步干扰的关键技术。FPGA is becoming the technology in digital signal processing in recent years. The navigation radar interface board takeing FPGA as its core control and treatment chip to carry out the pretreatment of radar azimuth, sync and video is introduced in this paper. The computer controls and monoitors the system through communication with the NIOS soft-core on FPGA. Furthermore, the key technology of anti-jamming is also discussed in this paper.
