The physical basis of SRS process in transparent droplets caused by intensive pumping radiation is considered. The vector Maxwell equations, where the nonlinear polarization is the source for Stokes field origin, are used as a starting point for theoretical analysis of SRS process in a droplet. In stationary case the expression for SRS threshold intensity is obtained. The values of the energy threshold of the SRS generation in droplets are evaluated depending on the droplets radius. The results of theoretical investigations of spatial structure of SRS field far from the droplet are represented also. The angular distribution of SRS is noted to be more homogeneous than elastic scattering diagram, what is connected with the absence of refracted on particle profile field component at Stokes frequency. In opposition to elastic scattering the angular SRS structure is practically symmetric with approximate period of pi/2. The results obtained are compared with the available experimental data.
