MULTI POLARIZATION MEASUREMENTS AND ESTIMATION OF REFLECTED SIGNAL MAGNITUDE VARIATIONS CAUSED BY TURBULENCE
Journal Title: Вісник Національного Авіаційного Університету - Year 2018, Vol 75, Issue 2
Abstract
The aim of this paper is the development of new polariza tion approach to evaluate the impact of dynamic atmosphere phenomena including turbulence into reflect ed 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 dy namic atmospheric phenomena influence. The expressions for the electromagnetic field scattered by liquid hydrom eteors 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 c ause the reflected signal variation is obtained. Calculation of the relation between the average signal value and the vibrations m agnitude in decibels was made to demonstrate the possibility to fix the reflected electromagnetic wave energ y variation caused by wind and turbulence. The results of the paper can be used for segregation of re flected signal magnitude variation due to the wind related phenomena including turbulence and other factors
