Vela Supernova remnant (SNR) is one of the nearest SNRs to Earth and serves as a space laboratory of relativistic and pulsar astrophysics. In particular, its synchrotron radio emission is determined by physical processes both in the remnant and in pulsar wind nebula (PWN), that resides in central part of remnant. In our work we separate the total radio flux from Vela SNR on fluxes from remnant and from PWN. It is shown that flux from the remnant is detected in MHz- range and is generated in the whole volume of remnant with uniform emissivity, while as flux from PWN is detected in MHz-GHz range and is generated in the spherically symmetric volume of PWN (MHz halo component) and in two additional sources: Northern and Southern pulsar wings (MHz-GHz wings).
