    An approach to discrimination of hydrometeors with similar polarization properties within the resolution volume
    (2016) Averyanova, Yulia; Yanovsky, Felix
    In this paper the possibility to distinguish hydrometeors with similar polarization properties inside the reflecting volume and estimating their differential impact onto polarization properties of reflected signal is made. The results are important for different practical application of radar meteorology including drop size distribution estimate, rainfall intensity estimate, wind speed measurement, turbulence and strong wind shear detection.

    Copula Analysis of Full Polarimetric Weather Radar Complex Signals
    (2016-10) Yanovsky, Felix; Rudiakova, A.N.; Sinitsyn, R.B.; Averyanova, Yulia
    In this paper we propose the method of transition from the complex full polarimetric radar signals to univariate uniformly distributed marginals that can be used for more precise copula analysis of statistical dependence between the complex samples of signals received at orthogonally polarized sounding waveforms. The method is applied to meteorological radar signal processing.

    Polarimetric Method to Discriminate the Drops on Sizes within the Resolution Volume
    (2016 International Conference on Mathematical Methods in Electromagnetic Theory, 2016) Averyanova, Yulia; Yanovsky, Felix
    In this paper we consider possibilities of radar polarimetry to solve different meteorological tasks including identification of atmospheric pfenomena microstructure and hydrometeor orientation, hydrometeors size measurement, wind related phenomena estimation. The potentials and restrictions of radar polarimetry are discussed. The approach that allows to increase informativity of polarization measuremens by distinguishing hydrometeors with similar polarization properties inside the reflecting volume and estimating their differential impact onto polarization properties of reflected signal is presented. The overvew of the polarimetric system with multiple receiving antenna system for aproach realization is done. The results are important for different practical applications of radar meteorology including drop size distribution estimate, rainfall intensity estimate, wind speed measurement, turbulence and strong wind shear detection.

    Turbulence intensity classification based on estimating statistical polarimetric parameters of radar reflections from rain
    (Telecommunications and Radio Engineering, 71(4), pp:379-385, 2012) Averyanova, Yulia; Yanovsky, Felix; Averyanov, A.
    In this paper the polarimetric approach for wind phenomena detection and study is proposed and analyzed. The polarimetric estimation of turbulence intensity is made with single unipolarized antenna radar system. The turbulence intensity classification based on statistical parameters of radar reflections from rain is made.
