Recently we have shown that the asymmetric lateral coherence of betatron radiation is characterized by peculiar properties that are evidenced with the analysis of the coherence factor of radiation. We extend such results to radiation emitted by ultra-relativistic proton beams in a 2-periods undulator. Results of a 2-dimensional simulation show that the real analysis of the asymmetric lateral coherence substantially improves the resolving power, thus transverse beam non-uniformities and the beam size can be measured at large distance.
