<title>Observation of transverse object mobility against the background of nonuniform medium in approximation of direct or back multiple coherent-wave scattering</title>

Abstract

The present paper examines location equations describing direct and back scattering of electromagnetic waves on an object moving against the background of nonuniform medium transversally to the direction to the receiver. The radial Doppler signal component is missing in this case. The multiple scattering on nonuniformities of the medium of background and object resulting in the Doppler background signal component is considered in the coupling wave approximation with the aid of the projection operator technique. In addition to the traditional background and transverse Doppler components resulting from scattering on medium nonuniformities, the obtained equations comprise the background Doppler and the background shadow components due to wave scattering on medium nonuniformities. The results of this study are applicable to investigations of liquids by optical beating spectroscopy methods, and to investigations of the atmosphere by means of location in the optical, infra-red and radio bands. The results of the experimental study of nonuniform liquid media by optical beating spectroscopy at small-angle scattering are observed.
