dc.description.abstract	Much attention is paid to studying the statistical properties and models of output signals in optical-television systems, post-detection processing methods. Despite the wide use of the Poisson and Gaussian models for describing the output signals due to their relative simplicity and possibility of obtaining analytical results, an adequate description of real processes requires taking into account the influence of abnormal emissions when registering optical radiation and fluctuations of transfer coefficients of receiving paths of optical-electronic systems. Modern methods of signal detection under a priori uncertainty are quite effective for the Poisson and Gaussian statistics, while abnormal emissions in the received optical field can significantly distort the estimates of system detection characteristics as a whole. Statistical properties of the output signals in the opticaltelevision systems with limited dynamic range taking into account interaction between the input radiation and optical link are considered in the paper. The model of á-stable processes was used to describe signals. Limiting distributions of the output signals are analyzed for belonging to the domain of attraction of the normal and stable laws with the characteristic indicator á. The asymptotic behavior of the distribution function of the output signals in the optical-television systems with limited dynamic range is experimentally verified and the applicability of generalized limit theorems is proved. Using the proposed model will allow to avoid conflicts between experimental data and existing mathematical models of output signals, and can be a theoretical basis for extending the dynamic range of opticaltelevision systems	uk_UA
