On the Role of Reflectarrays for Interplanetary Links

Abstract

Interplanetary links (IPL) serve as crucial enablers for space exploration, facilitating secure and adaptable space missions. An integrated IPL with inter-satellite communication (IP-ISL) establishes a unified deep space network, expanding coverage and reducing atmospheric losses. The challenges, including irregularities in charged density, hardware impairments, and hidden celestial body brightness are analyzed with a reflectarray-based IP-ISL between Earth and Moon orbiters. It is observed that 10810^{-8} order severe hardware impairments with intense solar plasma density drops an ideal system's spectral efficiency (SE) from  ⁣38 (bit/s)/Hz\sim\!38~\textrm{(bit/s)/Hz} down to 0 (bit/s)/Hz0~\textrm{(bit/s)/Hz}. An ideal full angle of arrival fluctuation recovery with full steering range achieves  ⁣20 (bit/s)/Hz\sim\!20~\textrm{(bit/s)/Hz} gain and a limited beamsteering with a numerical reflectarray design achieves at least  ⁣1 (bit/s)/Hz\sim\!1~\textrm{(bit/s)/Hz} gain in severe hardware impairment cases.
