Abstract
We study reabsorption of resonant transition radiation (RTR) of fast particles in a magnetoactive plasma with random inhomogeneities of electron density. The RTR growth rates are obtained for isotropic and anisotropic distribution functions of fast electrons. The coefficient of radio wave absorption by thermal electrons near the plasma frequency is obtained. It is shown that the RTR instability can be realized in the case of sufficiently strong anisotropy. The properties of such maser transition radiation allow us to distinguish it from other coherent mechanisms of radiation when interpreting laboratory and astrophysical observation results.
