Abstract

This paper presents the budget method of the Mars-earth communication link. The calculation models of Mars atmosphere loss, Mars sandstorm loss, solar scintillation loss, earth atmosphere absorption; rainfall loss and hot body noise are studied. The propagation characteristics of electromagnetic waves in Mars atmosphere are analyzed and modeled by the characteristics of the propagation of analogous waves in the Earth's atmosphere. Ultimately, we found that the surface of the radio waves propagation environment is ideal, with less attenuation loss. Especially, the calculate model of solar scintillation loss and rainfall loss is simulated, and the simulation results are consistent with the actual statistical results, which proves the rationality of the calculate model. At last, an example of Mars-earth communication link budget is given. With the procedure, we can get one of the most important parameters of the link-- Carrier to Noise Ratio, and we know the bit signal to noise ratio required by the right BER, then the maximum code rate of the link can be got. This paper has some reference to the design of Mars communication link.
