摘　　要：论述了噪声调频干扰理论，分析了混沌序列的性能，并对其进行了仿真研究，设计了基于混沌伪随机序列调制的数字噪声干扰源，给出了原理样机并得出测试结果。该干扰源具有干扰带宽、干扰中心频率可调、调制噪声带宽可程序控制等特点。Noise FM jamming theory is introduced; Chaotic sequence is analyzed and its performance is simulated. Digital noise modulated jamming source is designed based on chaotic sequence, prototype and test results are presented. The designed jamming source has tunable bandwidth and center frequency, and the modulation bandwidth of the noise can be controlled by the MCU.
