In job the questions of functioning interferometric SAR in jamming conditions are considered. The purpose of job is the reception of expressions for density of distribution of a difference of phases of readout of the complex SAR images, at the end allowing to pass to an estimation of an overall performance interferometric SAR in jamming conditions. For achievement of the specified purpose in clause are set Gaussian model of an backscattering signal of a permitted element of a surface and noise, then the kind of density of distribution of a phase difference for two cases - single-pass and repeat-pass interferometric of shooting of a relief of a terrestrial surface is defined at the attitude a signal / noise not smaller three. In both cases the distribution of phase differences submits to the Student-s distribution with two degrees of freedom not having than the central moments is higher first. In this connection as measures of disorder of a phase difference such characteristics of distribution are chosen, as probable error, the expressions for which also are given in paper. The analysis of these expressions has shown, that, as against repeat-pass, in case of single-pass meaning of disorder of an estimation of a phase difference is defined not only parity of noise and backscattering signal of a permitted element of a terrestrial surface levels, but also their mutual accommodation.
