signal extraction method meaning in Chinese
信号提权
Examples
- The tv goniometer is the ground control equipment of a model of anti - tank missile . it uses two ccd cameras and the signal extraction method of background counteract , which can make the guiding process of anti - tank missile wo n ' t interfered by sunlight , firelight of battle field , light , flame tracer etc . it can greatly improve the anti - interfering ability of the anti - tank missile system
该电视测角仪是某型反坦克导弹武器系统的地面控制设备，它采用两个ccd摄像机和背景抵消的信号提取方法，可使反坦克导弹的制导过程不受太阳的反光、战场的火光、灯光、曳光弹等干扰。 - An automated de - noising algorithm based on the energy of wavelet packet not donoho ' s threshold algorithm is established . a gear feature vibration signal extraction method using the wavelet packet energy is proposed , which can separate gear meshing vibration , noise vibration and gear fault vibration signal from the original gearbox case vibration signal . basis pursuit ( bp ) algorithm is introduced into the filed of mechanical signal de - noising and feature extraction for the first time
第三章摆脱了donoho的阈值消噪思想，从能量的角度建立了基于小波包的自动消噪算法；提出基于小波包能量分布的齿轮故障特征信号提取方法，可以将齿轮啮合振动信号、干扰振动信号以及故障冲击振动信号从原始齿轮振动信号中分离出来；首次将基追踪消噪算法引入到机械故障信号的消噪与特征提取上，通过对齿轮故障信号的消噪，表明了它的有效性，并对影响该方法实际应用效果的因素进行了全面的分析，同时也指出了该方法存在的局限性。
