Frequency content of randomly scattered signals

In this paper we consider a general hyperbolic system subject to random perturbations which models wave propagation in random media. We consider the paraxial white-noise regime in which the propagation distance is much larger than the diameter of the ...

For over 70 years it has been assumed that scalar wave propagation in (ensemble-averaged) random particulate materials can be characterized by a single effective wavenumber. Here, however, we show that there exist many effective wavenumbers, each ...

A parallel algorithm to solve the problem of seismic source location inside a randomly heterogeneous medium is considered. To recover the source position, we propose using information about recorded seismograms on the free surface and the ...
