Annotation: The article considers the issues related to error determining in the magnitude of the modified differential radar reflectivity that occurs when probing an inhomogeneous medium filled with hydrometeors on the polarization characteristics of the electromagnetic waves propagating in it. An approach is proposed to define the variability trend of such an error for various values of precipitation intensity, values of the anisotropy degree of meteorological formation and the orientation angles of eigenbasis of the remote anisotropic region, as well as the orientation angles of the measuring polarization basis. The obtained error estimates allow evaluating the regions with underestimation of the true estimation value of the anisotropy degree of the meteorological object
