Error of determination of radio-brightness temperature and temperature of plasma electrons

In our time, plasma physics is a hot topic of research. During the movement of a hypersonic aircraft, the main physical phenomenon, which radically affects the conditions for the propagation of electromagnetic waves in its vicinity is the formation of a plasma shell around the apparatus due to the ionization of neutral particles. When measuring the radio-brightness temperature and the temperature of plasma electrons, it is necessary to take into account the measurement error. In this article, these measurements are carried out, and the dependence of the root-mean-square relative error of temperature measurement on the power division factor is also given.
