Spectral Method of Synthesis of Geometric Models of Surface-Distributed Objects

Synthesis of Partially Coherent Geometric Models of Radar Objects Based on Their Incoherent Models

“…The next step toward reducing the number of points is the transition to partially coherent models, in which radiations from the points are statistically related and correlated. A two-dimensional partially coherent geometric model containing only four points located in the vertices of a square is known (Artyushenko et al, 2018). Correlated normal random processes with the given proper correlation properties (B i (τ) and C i (τ)-correlation functions of the similar and dissimilar quadrature components, the signal emitted from the ith point of the model) are brought to the points of such a model.In Stepanov and Kiselev (2019), the possibility of transition for one-dimensional incoherent models to partially coherent ones is proved based on the equivalence of the two-point partially coherent and three-point incoherent model.…”
