Research on Blackout Measurement and Communication of Reentry Vehicle

Abstract

For measurement and communication interrupt between earth station and reentry vehicle in blackout area, we analyze electromagnetic environment characteristic of plasma sheath. Methods of changing electrical characteristic of plasma medium or changing measurement and communication equipments are researched based on the analysis. Also technology of trajectory reconstruction is presented by using limited measurement data of target. The paper introduces technology status of measurement and communication for blackout area reentry vehicle. Also we analyze properties of common methods and propose key questions to research. It provides reference for related researchers.
