Applied Physics and Mathematics Annotation << Back MODELING OF USE OF A USEFUL LINEAR-FREQUENCY SIGNAL IN A SYSTEM OF DISTRIBUTED RECEIVERS IN A WATER TRANSPORT A.V. FROLOV The detection and isolation in space of a distributed time signal is a task in the general formulation that is relevant, but difficult to solve in a nonlinear version. To solve the problem with a linearly defined frequency-modulated signal in radar, a number of effective methods have been developed. The purpose of this work is to propose a procedure (algorithm) for processing signals and suppressing noise in water transport flows, systems in a linear version. If the Bayesian approach is applied, then with a small number of interference arrival (fixation) nodes and a high identification accuracy, the correlation matrix can be close to degenerate. A method based on Markov processes is used. From the broadband signal, a useful signal with linear frequency modulation in time is extracted, which is then transformed into a narrowband signal with a base close to unity. The model of autoregression, linear prediction (phase front) is used. Keywords: spatial, temporal, distributed, signals, Markov, process, random, system. DOI: 10.25791/pfim.01.2022.1219 Pp. 06-09.
