Abstract: Power plants with a charge of solid propellants are widely used in rescue systems, oil production, management, and rocket and space systems. The most advanced wave methods of investigation of such facilities include ultrasonic and microwave techniques. The existing methodological framework, based on correlation procedures and Fourier-analysis does not allow for efficient processing and presentation of test results. This leads to the creation of specialized software systems of modeling and digital processing of the results based on the use and development of the theory of the wavelet transform.

Keywords: non-destructive testing, signal-to-noise ratio, Fourier analysis, wavelet transform, ultrasonic method.
