Abstract

One of the major problems of remote sounding is determining the relations between the characteristics of echo-signals and the state of the scattering objects. In some cases the total solution of this problem in an experiment goes with unresolvable difficulties. Some very important practical results could be gotten, if experiments are being combined with mathematical and imitative simulations. A model of the processes of inverse scattering in atmospheric aerosols during sounding with pulse signal is being worked out. In the model considerations were made of the dielectric permeability, form and orientation peculiarities of the scatterers, their size-distribution, wind and turbulent pulsation characteristics, movement effects of the locator, and the beam-scanning effects. One of the peculiarities of the approach used in the model is separating the scattering volume not only into series of physical separate parts but also into series of partial components that are obliged to different groups of scatterers' sizes. The research done through imitative and statistical modeling allowed us to know the statistical characteristics of the echo-signals with respect to turbulent intensity. The received data agree with experimental results. They can be used in many practical applications. 11
