Statistical Characteristics of Martian Equatorial Ionosphere based on MARSIS

Abstract

In calibrating the Martian ionosphere effects in subsurface detection of MARSIS (Mars advanced radar for subsurface and ionospheric sounding), total electron content (TEC) of the Martian ionosphere is yielded as a by-product. Using these data, the peak electron density and scale height of Martian ionosphere in equatorial region is calculated. The result shows in equatorial region Martian ionosphere is more obvious in winter than in summar and the gradient of eletron density of Martian ionosphere in spring is of the biggest.
