声强检测可以有效地进行目标方位估计，利用频带划分、旋转波束、矢量方程组可以在一定程度上有效地解决多目标干扰的问题。 - The transform uses the scale of the signal to decompose and make self - adapting frequency band partition of the input signals . therefore the amplitude value and the modulating frequency of the flickering signal can be obtained . with the instantaneous frequency in this method , the present study also analyzes the signal in terms of both time and frequency , and thus gets the time at which the flickering signal occurs and terminates
运用该变换从信号本身的尺度特征出发对信号进行分解的特点,对输入信号进行自适应的频带划分,从而求出了闪变的调制信号幅值和调制频率;利用该方法中的瞬时频率概念,从时频两方面同时对信号进行分析,从而获得了闪变信号的发生时刻和终止时刻,得到了较好的检测效果。 - The feasibility of using mallat algorithm to extract the feature component of rotor bar faults is discussed , and we find that mallat algorithm is not suitable for rotor bar faults detection because of the similar representations of the fault and the normal signals
分析了应用mallat小波变换快速算法提取转子断条故障特征的可行性，指出由于故障信号与正常信号在时频域上的表现非常接近，仅使用基于频带划分的多分辨率分析方法的mallat算法难以提取出明显的转子断条特征量。
