Paper Abstract

Solution of practical problems of remote sensing in homogeneous atmosphere is based on the connection among parameters of sources and atmosphere inhomogeneities and spatial-temporal structures of the received signals. In this investigation we represent the effective technique: transferal coefficients (TC) for the solution of the problems of source and inhomogeneity probing in the refractive waveguides. We propose using the coefficient of energetic coupling and the anisotropy coefficient and mean time reaching, dispersion of the reaching time, and probability of differentiation of direct and scattered signals. The properties of the TC are determined only by the properties of temperature and sound velocity distribution in waveguides. The application of TC of inhomogeneous refractive atmosphere gives us the possibility to construct a priori spatial-temporal structure of background in the case of remote sensing of sources and to investigate the form of observation region and some of the spectral characteristics when we want to probe the inhomogeneities. We represent the calculated spatial maps of TC for the different types of waveguides. The possibilities of the calculation of these maps for the waveguide with localized inhomogeneities and the problems of optimization of receiving systems are discussed.
