| 摘 要： | 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。为提高线性调频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线性调频引信中,对噪声调幅干扰进行抑制。分析了噪声调幅干扰抑制原理,并对噪声调幅干扰抑制效果进行了仿真。仿真结果表明:SJB=-10 d B时,仍然能达到很好的噪声调幅干扰抑制效果。

| Abstract: | Noise AM interference is an effective suppressing jamming which can prevent a proximity radio fuze to get targetinformation. In order to improve the ability of linear frequency modulated fuze to anti-noise AM interference, notch filterwas adopted to suppress noise AM interference. The principle of anti-noise AM interference was analyzed and the sup.pressing effect was simulated. The simulation results showed that when SJR=-10 dB, noise AM interference could be stillsuppressed effectively. |
