Abstract— The D region of the ionosphere (60-90 km) is very important for a variety of radio science applications. It utilized is Web31 dec. 1993 · Recently, several tomographic techniques for ionospheric electron density imaging have been proposed. These techniques reconstruct a vertical slice image of electron density using total electron content data. The data are measured between a low orbit beacon satellite and fixed receivers located along the projected orbital path of the …
WebHis studies deal with areas such as Kalman filter, Tomography, Troposphere and Ionosphere as well as Global Positioning System. The Geodesy study combines topics in areas such as Abel transform and Total electron content. His GNSS applications research incorporates elements of Snow, Satellite navigation, Waveform and Orbiter. WebDue to the dispersive nature of ionosphere and the existence of Earth’s magnetic field, the polarization rotation of a linearly polarized wave will occur after traveling through the ionosphere. This phenomenon is known as Faraday rotation (FR) and depends on the frequency, the electron density, the Earth’s magnetic field, and the geometry of …
