Влияние движения сред на отражение упругих волн от подвижной границы

Considers the impact of the movement environments, adjacent to the boundary of the reflection and refraction of waves through mobile border section environments. Flow essentially changes the character of reflection from a moving boundary line, especially in the case when these speed comparable to a numerical value. Flow leads to an additional (to the Doppler) change in frequency of the reflected and passed the waves. Relationships are obtained: for the calculation of the frequency of the reflected and reaffirmed by the waves, for the calculation of the reflection and transmission coefficients, which generalize the well-known formula of Doppler effect for the case of moving borders and the media. Selection of speed of movement of media boundaries and velocity environments, you can achieve the absence of the reflected signal.
