The aim of this paper is the development of new polarization approach to evaluate the impact of dynamic atmosphere phenomena including turbulence into reflected radar. In this paper the liquid hydrometeors (raindrops) are considered as objects with unstable shape. Therefore, parameters of liquid hydrometeors are random characteristics that are susceptible to dynamic atmospheric phenomena influence. The expressions for the electromagnetic field scattered by liquid hydrometeors for the multi polarization radar system as well as a variable component of scattered field are obtained. The expression of phase detection for separation of turbulence from other factors that cause the reflected signal variation is obtained. Calculation of the relation between the average signal value and the vibrations magnitude in decibels was made to demonstrate the possibility to fix the reflected electromagnetic wave energy variation caused by wind and turbulence. The results of the paper can be used for segregation of reflected signal magnitude variation due to the wind related phenomena including turbulence and other factors.
