Analysis of Terahertz Communication Under Dust Storm Conditions on Mars

Abstract

This letter explores Terahertz communication in Mars surface channel models, analyzing Terahertz communication applicable to Mars through Mars-related simulations. Firstly, the basic components and system model of the Terahertz frequency communication system are discussed. Secondly, simulations involving data rate, frequency, transmission distance, power budget, dust density, and signal-to-noise ratio reveal the main relevant factors of Terahertz communication on Mars. The study focuses on signal transmission in the Mars environment under thin Martian air and intense dust storms, analyzing the impact of transmission distance, air molecule absorption, and dust particle scattering. Additionally, this letter examines Terahertz channel coding and capacity analysis in the special Martian environment, aiming to more accurately assess the feasibility of applying Terahertz communication to the Martian surface. Finally, the wireless link is validated through simulations, demonstrating its capabilities and limitations.
