摘要

Exile of Bayesians approach from mathematical statistics hampered development of stable theory of CFAR and STAP. Many heuristic corrections appeared therefore to various aspects of these theories. But, it seems better to begin creating the generalized Bayesians theory, following which one can obtain the processing algorithms in fast varying conditions without corrections. A priory statistical model of TI was reasoned with this purpose as the Pareto-Gaussian (PG) process belonging to SIRP ones. Preference of PG process consists of its simplicity and compatibility with CFAR -STAP problems. The PG model allows accounting for: (1) (Quasi Gaussian TI of highest entropy (η = 0); (2) essentially non Gaussian TI (η< - 1/2).
