Scattering Performance of Terahertz Channels by Space Debris

With the rapid advancement of wireless communications, there is a growing demand for higher data transmission rates. High-frequency, wide-band terahertz communication technique has emerged as a crucial method for achieving high-bit-rate data transmission. Utilizing the terahertz frequency band for satellite communication offers the potential for low-latency, wide-coverage global coverage, and addresses the pressing requirements of low-orbit broadband and large-capacity satellite communication. However, when it comes to satellite communications, it is essential to take into account the impact of space debris on channel performance. This work delves into the transmission characteristics of terahertz channels when encountering space debris within a laboratory setting. The sample we used, representing a group of space debris, is fabricated using metal sheets composed of an aluminum-tin mixture. For experimental purposes, channels operating at 120GHz, 160GHz, 220GHz and 320GHz are employed. This investigation encompasses an exploration of terahertz channel scattering and reliability.
