火箭发动机厚层包覆质量的信号处理

对于火箭发动机装药包覆胶接状态和包覆层厚度的诊断，利用小波在应有频率与时段上的重构，基本恢复出理想的检测信号，这种检测方法针对层厚处伴有噪声干扰时的微弱信号检测有较好的效果。

Signal Processing of Thick Coating Quality for Rocket Motor

To diagnose the binding quality and the coating layer thickness of the solid rocket motor , an approach for resuming the ideal signal by the wavelet reconstruction on the useful time field and frequency field is presented in this paper. The approach is effective to monitor the faint signal with the noise at the thick layer position.
