Abstract

Scattering from a non-smooth random field on the time domain is studied
for plane waves that propagate simultaneously through the potential in
variable angles. We first derive sufficient conditions for stochastic
moments of the field to be recovered from empirical correlations between
amplitude measurements of the leading singularities, detected in the
exterior of a region where the potential is almost surely supported. The
result is then applied to show that if two sufficiently regular random
fields yield the same correlations, they have identical laws as
function-valued random variables.
