THE FEATURES OF MODERN METHODS OF ESTIMATION AND FILTERING OF SIGNALS

The paper considers the peculiarities of signal processing in radar systems based on the methods of filtering and parameter estimation. The conditions that are required in order to estimate the parameters of the signals, is usually performed for stage processing of radar signals, which is based on special signal processors are shown. The characteristics of primary and secondary radar data are marked. In the models presented on the basis of stochastic differential equations that provide: models associated with the continuous change of the parameters and models associated with the continuous quasi-linear filtering. The analysis of models related to the estimation of the parameters of intense maneuvering objects, which did not provide a clear transition to the algorithms related to nonlinear filtering.
