噪声调幅干扰是一种有效的压制性干扰，可压制近炸无线电引信对目标信息的获取。为提高连续波多普勒无线电引信抗噪声调幅干扰的能力，将单频率自适应陷波器应用到连续波多普勒引信中，对噪声调幅干扰进行抑制。分析了噪声干扰抑制原理，并对噪声干扰抑制效果进行了仿真。仿真结果表明：SJR=-10 dB时，仍然能达到很好的噪声调幅干扰抑制效果。

Noise AM interference can prevent a proximity radio fuze form getting target information. In order to improve the ability of continuous-wave Doppler fuze to anti-noise AM interference, notch filter was adopted to suppress noise AM in-terference. Principle of anti-noise jamming was analyzed and the suppressing effect was simulated. The simulation results showed that when SNR=-10 dB, noise AM interference could still be suppressed effectively.
