Under the project National Heliogeophysical Complex of the Russian Academy of Sciences, it is planned to create several coherent decameter radars. ISTP SB RAS developed a network of coherent decameter radars well before the start of financing this project. This has provided extensive experience in operating such radars, has enabled us to identify their technological problems, which should be solved when creating radars of own design, and to develop a project of radars with broader capabilities for diagnostics of the ionosphere as compared to existing radars of similar types. The paper analyzes the existing EKB ISTP SB RAS radar, reviews its technological problems, and proposes the structure of a new radar of SECIRA type. We report the results of prototyping of elements of the SECIRA radar, which demonstrate the possibility of its implementation. We discuss the potential applicability of the radar to ionospheric studies on the territory of the Russian Federation, in particular in high-latitude regions.
