The architecture of a promising distributed system for digital processing of radar data

Бесплатный доступ

The article is devoted to the development of a proposal for the architecture of a system for digital processing of radar data on a domestic element base. The research was initiated by the study of the functioning of integrated circuits based on processors “Multicore”. In the proposed material, the structure of the input stream of Earth radar observation data and the algorithm for their processing are considered. The scheme of distributed data processing using a parallel computer is built. A scheme of a digital data processing system using a two-tier architecture is proposed. A change in the scheme in the form of optimization for the use of the fast Fourier transform in base 4 is proposed. Two variants of implementation are shown, and an estimate of the computational efficiency of this transition is given. The practical significance of the research presented in the article lies in explicitly proposing the structure of a solver that has a higher computational efficiency compared to a similar one that uses the fast Fourier transform in base 2, as well as in the development of a scheme for including such decisive (computational) nodes in a computational cluster. The place of the control module, which forms a dynamic plan for the use of resources, is shown. This material will be of interest to radio amateurs, as well as to students and workers in the field of radar surveillance data processing.
