  The next generation interferometric radio telescope, the Square Kilometre
Array (SKA), which will be the most sensitive and largest radio telescope ever
constructed, could greatly contribute to the detection, survey and
characterization of Gamma Ray Bursts (GRBs). By the SKA, it will be possible to
perform the follow up of GRBs even for several months. This approach would be
extremely useful to extend the Spectrum Energetic Distribution (SED) from the
gamma to the to radio band and would increase the number of radio detectable
GRBs. In principle, the SKA could help to understand the physics of GRBs by
setting constraints on theoretical models. This goal could be achieved by
taking into account multiple observations at different wavelengths in order to
obtain a deeper insight of the sources. Here, we present an estimation of GRB
radio detections, showing that the GRBs can really be observed by the SKA. The
approach that we present consists in determining blind detection rates derived
by a very large sample consisting of merging several GRB catalogues observed by
current missions as Swift, Fermi, Agile and INTEGRAL and by previous missions
as BeppoSAX, CGRO, GRANAT, HETE-2, Ulysses and Wind. The final catalogue counts
7516 distinct sources. We compute the fraction of GRBs that could be observed
by the SKA at high and low frequencies, above its observable sky. Considering
the planned SKA sensitivity and through an extrapolation based on previous
works and observations, we deduce the minimum fluence in the range 15-150 keV.
This is the energy interval where a GRB should emit to be detectable in the
radio band by the SKA. Results seem consistent with observational capabilities.
