The problem of microwave thermal emission from a half‐space random medium is solved. We consider a laminar structure which has a nonuniform temperature distribution in the vertical direction. A radiative transfer approach is applied. For constant absorption and scattering coefficients, the brightness temperature is determined by a simple closed‐form formula. Physical interpretations and numerical results are illustrated and discussed for the various cases.
