  Deuteron-proton elastic scattering is considered at the energies from 880 MeV
to 2 GeV at the scattering angles $\theta^*\ge 140^\circ$. The
multiple-scattering method is used to calculate the reaction amplitude. Four
reaction mechanisms are taken into account: one-nucleon-exchange,
single-scattering, and double-scattering with a nucleon and a delta-isobar in
the intermediate state. The method allows calculating both unpolarized
differential cross section and any polarization observables.
  All the results obtained are compared to the experimental data.
