Abstract

With the successful completion of a field demonstration of uplink arraying at 8 GHz (X-band) using real-time atmospheric compensation enabled by phase transfer rather than time transfer techniques- completion in mid-Aug 2010, NASA is interested in demonstrating a similar capability at 30-31 GHz (Ka band). Such a demonstration would enable NASA to establish [a] a high power, high resolution, 24 / 7 availability radar system for characterizing observations of Near Earth Objects, determining the statistics of small [≤10cm] orbital debris, [ b ] to incorporate the capability into its space communication and navigation tracking stations for emergency spacecraft commanding in the Ka band era which NASA is entering and [c] to field capabilities of interest to other US government agencies. We describe a a project of Evolutionary Steps Leading to Revolutionary Increases in Capability and Capacity
