The practical applications of surface plasmon polaritons (SPPs) require thedeep understanding of the impact of electrical characteristics variability andgeometrical irregularity of the metal-dielectric interface. Traditional methodsin the theory of wave scattering at rough interfaces fail to treatsimultaneously the interference (Anderson) localization of the SPP, which mayarise due to its multiple back-scattering by random distortions of surfacerelief, and the leakage into the uniform dielectric half-space. In our previousworks [Low Temp. Phys. \textbf{42}, 685 (2016); Ann.~Phys.~\textbf{455}, 169378(2023)], by representing the perturbation of surface impedance as an effectivepotential in the Schr\"odinger-like equation, we suggested the way to describethe interplay between Anderson localization and the leakage of the SPP. In thepresent study we show that the problem of SPP scattering from finitegeometrically rough region of the interface can be reduced to the problem ofits scattering from the same region but with effective random impedance. Wecalculate the radiation pattern and demonstrate its pronounced anisotropy thatarises due to the interplay between different geometrical parameters of theinterface roughness.
