| 中文摘要:现有的时频分析方法很难检测到某型导弹测角仪故障，针对这个问题，提出测角仪故障检测的连续和离散小波变换相结合的时频分析法。给出该方法提出的过程，分析连续和离散小波变换时频分析法，将两种分析方法的特点结合起来共同分析测角仪故障时的信号信息。通过仿真实验证明，提出的方法能准确的提取测角仪故障时的信号特征，对测角仪故障的检测是有效的。 |

| Abstract:Aiming at the problem of Existing time-frequency analysis methods is difficult to detect goniometer fault, combining continuous and discrete wavelet transform to analyse the signal. The process of the method proposed are given, Time-frequency methods of continuous and discrete wavelet transform are analysed. Characteristic of CWT and DWT combined to analysis goniometer fault signal information. The simulation show that the mean can accurately extract the goniometer fault signal characteristics and it is effective to the fault detecting. |
