The direction of the electric vector of synchrotron emission of ultrarelativistic particles is perpendicular to a magnetic field and to the direction of propagation of a photon. If the emitting volume of plasma moves relativistically, as it is the case for almost all extragalactic and galactic jets, Lorentz transformations of electromagnetic field and the direction of the propagation of the photon result in that the electric vector of the wave is no longer orthogonal to the magnetic field in the laboratory frame. This changes the interpretation of the astronomical polarization observations. Here we demonstrate the effect by calculating the polarization properties of synchrotron radiation emitted by a cylindrical relativistically moving jet with large scale ordered spiral magnetic field. Integrated polarization is bimodal, which is favoured by the observations. Small changes in the velocity and observing angle can produce a flip of polarization. Our simulated polarization maps are in agreement with observations, indicating that the jets are likely to posses spiral magnetic fields.
