  Using perturbative renormalization group we investigate the influence of
random velocity field on the critical behavior of directed bond percolation
process near its second-order phase transition between absorbing and active
phase. Antonov-Kraichnan model with finite correlation time is used for
description of advecting velocity field.
  The field-theoretic renormalization group approach is applied for getting
information about asymptotic large scale behavior of the model under
consideration. The model is analyzed near its critical dimension through
three-parameter expansion in {\epsilon}, {\delta}, {\eta}, where {\epsilon} is
the deviation from the Kolmogorov scaling, {\delta} is the deviation from the
critical space dimension {d_c} and {\eta} is the deviation from the parabolic
dispersion law for the velocity correlator. Fixed points with corresponding
regions of stability are determined to the leading order in the perturbation
scheme.
