Chandra observations of Tycho's supernova remnant (SNR 1572) allowed us to get high-resolution X-ray images of SNR. It was discovered that there are several series of coherent X-ray structures (bright, almost parallel stripes) in some regions of SNR. It is likely that the observed radiation of Tycho's SNR is synchrotron radiation of electrons with energies about 10{14} eV. We develop a model, which represents synchrotron X-ray images of Tycho's SNR in order to reveal the physical mechanism of the observed structures formation. The model allows one to connect the bright stripes with a specific mechanism of the energetic particle transport in SNR. In particular, it is shown that the mirror instability, which evolves in plasma near SNR shock as a result of anisotropic 22 distribution function of electrons, can be the reason of the observed stripes.
