Distributed Arrays and Signal Processing for the TechSat21 Space-Based Radar

Abstract

The TechSat21 space-based radar concept, suggested by AFRUVS, employs a cluster of free-floating satellites, each of which transmits its own orthogonal signal and receives all reflected signals. The satellites operate coherently at X-band. The cluster forms essentially a multi-element interferometer with a concomitant large number of grating lobes and significant ground clutter. This study explores some basic characteristics of such a system with respect to detection of slowly-moving ground targets (GMTI).
