Head Vasilevsky Vladlen Vasilyvich, Registration Date 09-08-2004 Organization Institute of the Land Forces.Odessa popup.description2 Theoretical results and theirs scientific innovation are: - method of analytical estimation of observed process Hermitian matrix sensitivity to random noise of Hermitian matrix elements is offered; method considers random noise which is present in estimation matrix elements of Hermitian structure; - analytical discrete picture deformation model, based on estimation matrix with different ranges of its conditionality, is suggested; estimation of matrix deformation operator is formed within test signal subspace; model permits to form the robust procedure of operator restoration; - mathematics of adaptive selection of estimation matrix regularization parameter are elaborated; mathematics have convergence to optimal regularization parameter value; - inverse discrete picture restoration system with regularization parameter adaptive selection is synthesized; - method of adaptive friendly signal detection against a background of arbitrary power spectrum jamming (APSJ ) is proposed; method provides for optimalinterconnecting of adaptive spatial discrimination method and adaptive polarization discrimination method into common algorithm; - mathematical model of processes of adaptive friendly signal detection against a background of arbitrary power spectrum jamming is proposed; - statistical model of processes of adaptive friendly signal detection against a background of arbitrary power spectrum jamming is proposed; - self-focusing radar image method is offered; it provides for simultaneous focusing of all reflectors in all distance resolution elements; method uses modified self-focusing criterion; - facet model for calculation the compound object scattering signature for monostatic location; model considers diffraction phenomenon and phenomenon of shading. Practical final results are: - well-behaved structure of adaptive spatial - polarization discrimination system is worked out; system ensures increasing effectiveness of signal detection against a background of jamming; - increasing of quality of inverse discrete picture restoration under conditions of prior uncertainty relative to random noise in estimation matrix elements is provided; - possibility of estimation of quality of inverse discrete picture restoration during system design is obtained; - restoration algorithm of radar image with simultaneous focusing of all reflectors in all distance resolution elements is proposed. Results of investigation are relating to multidimensional signal processing in information system. Product Description popup.authors popup.nrat_date 2020-04-02 Close
