Background ionospheric propagation effects are adverse to the performance of Geosynchronous Synthetic Aperture Radar (GEO SAR) system. This paper focuses on the background ionospheric phase advance. which can be modelled as a function of Slant Total Electron Content (STEC). The dispersive feature of the phase advance caused by the background ionosphere could be able to distort the GEO... https://bwcpowersports.shop/product-category/engine/
