radiotechnical tracking systems of extensive above-water object is proposed. This method is based on approximation coefficient comparison and threshold and filtering of detailing coefficients. Novel dynamic scene processing algorithms for parametric a priory uncertainty as a result of numerical modeling based on real data for large-capacity vessel pilotage in Dnieper-Bug leman proposed.
Coordinates estimation method of the extensive objects enhanced, recommendation on weighting coefficients and patch function usage for robustness of derived methods proposed Binary dynamic scene processing algorithm with neural network usage proposed. This algorithm is based on derived localization method of extensive objects against clutter background for stochastic and functionally-determined input signal models which gives higher performance and stability of the proposed methods. Results were applied in data-processing system of navigation set Liman NE Delta-Lotsman, Nikolaev.
Keywords: extensive object, optimal signal processing, non-stationary, wavelet transformation.Скачать
