| 摘 要： | 提出一种新的舰船轴频电场信号检测方法.该方法利用高阶累量对高斯噪声的抑制作用,首先使用基于自适应累量算法的FIR滤波器对接收信号进行滤波消噪处理,以提高信噪比;然后再对滤波输出信号进行滑动功率谱检测.实测数据处理结果表明了该方法的稳健性和有效性.

| Abstract: | An adaptive cumulant algorithm-based method is proposed for ship shfit-rate electric field signal detection.Firstly,a cumulant-based adaptive FIR filter was used to de-noise the received noisy signal.Then,the enhanced signal was detected based on moving power spectrum detection algorithm.The results show that the proposed method is practical and effective. |
