Query: Reconstruction and Estimation of Scattering Functions of Overspread
  Radar Targets   In many radar scenarios, the radar target or the medium is assumed to possess
randomly varying parts. The properties of a target are described by a random
process known as the spreading function. Its second order statistics under the
WSSUS assumption are given by the scattering function. Recent developments in
the operator identification theory suggest a channel sounding procedure that
allows to determine the spreading function given complete statistical knowledge
of the operator echo. We show that in a continuous model it is indeed
theoretically possible to identify a scattering function of an overspread
target given full statistics of a received echo from a single sounding by a
custom weighted delta train. Our results apply whenever the scattering function
is supported on a set of area less than one. Absent such complete statistics,
we construct and analyze an estimator that can be used as a replacement of the
averaged periodogram estimator in case of poor geometry of the support set of
the scattering function.
