PROCÉDÉ ET SYSTÈME DE DÉCOMPOSITION DE CIBLES COMPOSITES SUR DES ÉLÉMENTS D'UNE SIGNATURE CIBLE DE RADAR À TRÈS HAUTE RÉSOLUTION, À L'AIDE DU SPECTRE DU SIGNAL TOTAL

摘要

This technical solution generally refers to computer engineering and specifically refers to methods and systems of the decomposition of composite targets into elements of the radar target signature. The method for decomposing the composite targets into elements of a radar signature of a super-resolution target, using the entire signal spectrum, where obtaining at least one radar image in the form of a radio hologram from a radar; determining by means of a computer the complex amplitudes and coordinates of bright points on the radar image obtained in the previous step, on the basis of an iterative procedure from brighter to less bright spots; subtracting by means of a computer the signals of bright spots from a previously received radar image, which results in a background image left; performing the smoothing of the obtained background image by using a filter suppressing the speckle noise; forming the output radar image, by means of a computer, on the basis of a set of bright spots with amplitudes, coordinates in azimuth and range, as well as a smoothed background signal. The technical result - improving the quality of processing the RI.
