Parameter sensitivity in nonlinear and dissipative time-reversed acoustics

Parameterkänslighet i ickelinjär och dissipativ tidsomvänd akustik (Swedish)
Abstract [en]

Time-reversed nonlinear acoustics has shown that a propagated signal retains information about the original signal after shock formation and even after merging of shocks. This information is dependent on the accuracy of the measured or calculated data . Presented here is a more detailed analysis of the estimation of dimensionless and real parameters in the problem - the original amplitude, the distance traveled and the dissipation over non- linearity ratio. It is shown that the methods are fairly insensitive to noise.

Abstract [sv]

Tidsomvänd ickelinjär akustik har visat att a signal kvarhåller information om dess begynnelsetillstånd till och med efter sammangående av stötarna. Här visas hur parametrarna i problemet kan uppskattas: begynnelseamplituden, fortplantningsavståndet och förhållandet mellan dämpning och ickelinjaritet.
