  Deuteron-proton elastic scattering is studied in the multiple scattering
expansion formalism. The four contributions are taken into account:
one-nucleon-exchange, single- and double scattering, and $\Delta$-isobar
excitation. The presented approach was applied to describe the differential
cross sections at deuteron energies between 500 and 1300 MeV in a whole angular
range. The obtained results are compared with the experimental data.
