The paper examines a spatial-polarization filter (SPF)employed for supression of two-beam, partially scattered interference. The operation of the filter is based on the assumption that two interference beams have different polarizations and incidence angles. Two versions of operation of such a filter are analyzed for the caser of supression of a two-rbeam concentrated interference in receiving a partially scattered two-beam signal in the presence of additive noise. Analytic expressions, controlling the possible gain in the signal/noise ratio when using this filter are obtained.
