| 摘 要： | 回波信噪比决定了引信在干扰/噪声环境下对目标的检测能力,提高信噪比是引信设计的关键内容.本文利用自适应滤波双通道干扰抵消算法,以背景通道接收到的杂波信号为参考,对主通道进行降噪处理.仿真及试验结果表明,该方法可使信噪比提高约14 dB.

| Abstract: | The detecting capability of fuze in complicated electromagnetic environment is determined by signal-noise ratio(SNR)of the echo,and improving SNR is the key problem in fuze design.In this paper an self-adaptive noise-cancellation technique is studied to denoise the main channel refrenced by the noise of background channel.The simulation result shows the SNR can be improved to 14 dB. |
