Precision characteristics of the differential radar reflectivity meter

The paper studies the questions relating to the analysis of the accuracy characteristics of the differential radar reflection meter as applied to radar probing tasks of the medium filled with hydrometeors. It is well known the efficiency of the differential radar reflectivity method has limited by its strong dependence on orientation angle between medium basis and radar polarization basis. The estimation of radar reflectivity measurement error is determined to such limitations. A new approach to the estimation of precision characteristics of the radar reflectivity meter has presented. The method had based on the use of dependence of the scattering matrix weight coefficient on the medium factors such as differential phase shift and differential attenuation. The particularity of proposed approach is calculation relations destined to the radar reflectivity variability determination and error measurement estimation. The calculation of the differential radar reflectivity and its error measurement estimation has presented. The given result is analyzed.
