Rotating mirrored aperture synthesis (RMAS) for passive microwave remote sensing

摘要

Aperture synthesis technique can provide high spatial resolution without requiring very large and massive real aperture. However, large aperture synthesis systems are very complicated. In this paper, Rotating Mirrored Aperture Synthesis (RMAS) is proposed, which combines rotating and mirrored aperture synthesis to improve spatial resolution with fewer antennas. The principle of RMAS is presented. The initial simulation result shows the RMAS system can approximately reproduce the brightness temperature image of the observed scene.
