摘　　要：噪声调频干扰具有宽的干扰带宽和较大的噪声功率,是目前对雷达、引信、通信进行阻塞式干扰中最常用的干扰形式。本文采用DDS技术,结合FPGA芯片结构特点,产生噪声调频干扰,改进了传统的设计方法,在置频精度、结构和速度方面有了很大的改善,具有一定应用价值。Noise FM jamming which has wide jamming band and large noise power is widely used in processing backup jamming to radar, fuze and communication. The paper adopt DDS combines with char-acteristic of FPGA chip to generate noise FM jamming. The method has large improvement in precision, structure and speed, and has broad application and prospect.
