Abstract: The simplest sinusoidal model of a symmetric textured surface observed with a noise being a homogeneous and isotropic Gaussian random field (in particular, a strongly dependent random field) on the plane is studied in the paper. The strong consistency and asymptotic normality of periodogram estimators of the amplitude and angular frequencies are proved for this model of the trigonometric regression.
