论文摘要

自1960年代以来,太空探索一直在上升。火星与水星,金星,土星和木星等其他行星一起在太空探索的历史中肯定发挥了重要作用,并且有可能成为第一个举办人类生命的外星星球。在这种情况下,已经为开发新技术来拍摄,测量和分析红色星球已经付出了巨大的努力。随着从周围和火星上收集的科学工具收集的数据量增加,地球和太空探针之间的快速和可靠通信的需求也出现了。但是,由于无线电波的传播特征,在深空沟通一直是一个巨大的挑战。如今,像SpaceX这样的私人公司与太空机构的合作使火星殖民化成为现实,引入了更多的挑战,例如在火星环境中提供高数据速率,低潜伏率,能效,可靠和耐药性通信基础设施。应该对火星的传播介质和无线通道特征进行广泛的研究以实现这些目标。这篇调查文章介绍了MARS任务和近地,星际和近场链路的渠道模型研究的全面概述。还审查了火星表面上三维(3D)通道模拟模拟的研究。我们还使用无线Insite软件根据现实的3D火星地形考虑了各种情况,展示了自己的计算机模拟。在本研究中,计算并表达了路径损失指数,功率延迟轮廓和根平方延迟延伸。此外,还提供了有关火星新兴通信技术的未来见解。

Space exploration has been on the rise since the 1960s. Along with the other planets such as Mercury, Venus, Saturn, and Jupiter, Mars certainly plays a significant role in the history of space exploration and has the potential to be the first extraterrestrial planet to host human life. In this context, tremendous effort has been put into developing new technologies to photograph, measure, and analyze the red planet. As the amount of data collected from science instruments around and on Mars increased, the need for fast and reliable communication between Earth and space probes has emerged. However, communicating over deep space has always been a big challenge due to the propagation characteristics of radio waves. Nowadays, the collaboration of private companies like SpaceX with space agencies to make Mars colonization a reality, introduces even more challenges, such as providing high data rate, low latency, energy-efficient, reliable, and mobility-resistant communication infrastructures in the Martian environment. Propagation medium and wireless channel characteristics of Mars should be extensively studied to achieve these goals. This survey article presents a comprehensive overview of the Mars missions and channel modeling studies of the near-Earth, interstellar, and near-planet links. Studies featuring three-dimensional (3D) channel modeling simulations on the Martian surface are also reviewed. We have also presented our own computer simulations considering various scenarios based on realistic 3D Martian terrains using the Wireless Insite software. Path loss exponent, power delay profile, and root-mean-square delay spread for these scenarios are calculated and tabularized in this study. Furthermore, future insights on emerging communication technologies for Mars are given.
