Paper Abstract

The present paper describes an adaptive range compression procedure for the compensation of the phase dispersion effects induced on low frequency radar echoes propagating through a ionized plasma, such as a planetary Ionosphere. The method is based on an equivalent model of the Ionosphere refraction index which outperforms currently available models in representing the ionosphere dispersion when the sounding frequency approaches the Ionosphere plasma frequency. The expected performance of the method is derived in the specific case of the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS), which will flight to MARS in 2003 aboard the Mars Express orbiter. Reported results indicate that the proposed algorithm gives acceptable residual distortions even when the operating frequency is very close to the ionospheric plasma frequency.
