INVESTIGATION OF THE INFORMATIVITY OF THE SIGNS OF SELECTION OF THE SPACECRAFT, FORMED BY THE RESULTS OF PROCESSING THE TEMPORARY REALIZATIONS OF NON-COORDINATE INFORMATION

Abstract

The article is devoted to the experimental study of the accumulated measurement information with the purpose of searching for an informative composition of the sign of selection for solving the problem of selection of space objects with an assessment of the expected indices of its quality and reliability. The results of the study of the possibility of using as an informative sign of selection for the solution of the problem of selection of spacecrafts for estimating its design features, as well as parameters characterizing its behavior in space as a rigid body, are presented. Studies are carried out for spacecraft, in the design of which there are largesized radar panels or fast-rotating elements. Estimations of the considered signs of selection are formed by radar non-coordinate information. An algorithm is developed for detecting a large-sized radar panel in a spacecraft structure and an algorithm for detecting fast-rotating elements in a spacecraft design and estimating rotational parameters using a discrete wavelet Haar transformation. The obtained results of the study are presented. The study of the quality of the signs of selection is carried out using interval parameter estimates.
