Abstract. The aim of this work is the practical development of the technology for synthetic aperture radars (SAR) testing using Digital Radio-Frequency Memory (DRFM). In this work, the methods of numerical mathematical modeling of interacting radio frequency systems in MATLAB and the methods for prototyping these systems using modular equipment from Keysight Technologies were used. And also, real manufactured devices (DRFM module) were used. In this work, the technology of synthetic aperture radars (SAR) testing using DRFM are discussed. The SAR prototype, built on the basis of modular equipment from Keysight Technologies and running under the MATLAB control is described. The structural and functional diagrams of the SAR model are considered, its operating modes are listed. A DRFM device, made on the basis of a VPX module with an FPGA and creating several arbitrary located simulated point targets on the SAR image is described. The structure of this DRFM is given. As a result of the work, a test radar image, formed by the SAR model as a result of processing synthesized in DRFM a digital radio-hologram (DRH), was obtained.
Key words: synthetic aperture radar (SAR), digital radio frequency memory (DRFM).
