PROCÉDÉ ET SYSTÈME D'ESTIMATION DES INSTABILITÉS DE TRAJECTOIRE DE VOL DE VÉHICULE AÉRIEN

摘要

This technical solution generally refers to the field of computer technology, and in particular to methods for estimating flight-path instabilities (EFPI) intended for use in radar image synthesis systems. A method for estimating the air vehicle flight-path instabilities, in which at least one radio hologram from the radar is obtained on at least one server, the hologram being a two-dimensional array consisting of complex numbers; the phase increments for each two adjacent columns of the hologram obtained at the previous step are estimated by the server; the range increments based on the previously determined by the server estimates of the phase increments for the hologram, are calculated; the increments of the air vehicle displacement coordinates are determined by the criterion of the mean square of the approximation error in order to approximate the range increments obtained earlier; the coordinates of the air vehicle displacement are determined by summing all the increments of the air vehicle displacement coordinates obtained at the previous step. The technical result is the improvement of radar image quality on any air vehicle in the event of strong flight-path instabilities, as well as an increase in the reliability of the on-board radar complex.
