Abstract
The paper considers approaches developed for the synthesis of a two-point geometric model that emits correlated signals and forms angular noise with given spectral-correlation properties, based on its equivalence of a three-point model that emits noncorrelated signals. Analytical relationships have been obtained that allow us to determine the spectral correlation characteristics of the signals supplied to the emitters of the two-point partially coherent model. The basis for the synthesis of a two-point model, emitting correlated signals, is a three-point model, emitting non-correlated signals. The considered models can replace a one-dimensional object that has the property of separating the spatial and temporal variables in functions that determine the distribution of the density of the auto- and cross-correlation quadrature components of the echo signal over the object. In this case, all points of the object being replaced reflect echoes with the same spectral and correlation properties. The obtained theoretical results are confirmed by digital modeling. The obtained probability density distributions of the angular noise and their correlation functions coincide for the two considered models.
