Pulsars are quickly rotating neutron stars which have ultra intensive magnetic field around them. In the vicinity of magnetic poles of such a star its rotation leads to generation of intensive electric field which has longitudinal component with respect to the magnetic field direction. This field can pull out the electrons from the surface of the star (which is supposed to consist of matter in atomic state - iron, nickel etc.) and accelerate them to considerably high energies (with the Lorentz-factor of the order of 10^7) within a short spatial gap. Such acceleration, together with a series of other radiation mechanisms (e.g. curvature radiation from the electron motion along magnetic field lines), leads to generation of narrow radiation pulses - main pulse (MP) and interpulse (IP) - emerging respectively from two magnetic poles of the star. The radiation is emitted in wide frequency range, - from radio to gamma, - and it is the peculiarities of radiation in radio band (of the order of several GHz) that we consider in the present work.
