Abstract
One method to dramatically reduce the weight, volume and associated cost of space-based Synthetic Aperture Radars (SAR) is to replace the conventional rigid manifold antenna architecture with a flexible thin-film membrane. This has been successfully demonstrated as a passive array. To further reduce the cost and weight and provide 2D scanning required by space-based applications we also need to integrate the Transmit/Receive (T/R) function into the inflatable antenna elements. This paper explores the constraints that must be placed on the active electronics of a flexible antenna array and preliminary work in this area.
