Investigation of the influence of the equatorial anomaly of the Earth's ionosphere on the propagation of radio waves in the P-band

Abstract:
The influence of the equatorial anomaly of the ionosphere on the propagation of radio waves in the P-band (430 MHz), planned for remote sensing of the Earth's surface from space, has been investigated. Calculations at three different points of reception on the Earth's surface are compared. The Faraday rotation of the plane of polarization, phase deviation and polarization coefficients are considered. The values of the angle of Faraday rotation and phase deviation are estimated. It is shown that during propagation, the circular polarization of radio waves at such frequencies practically does not turn into elliptical, except for the insignificant region.
