Abstract: In this letter, we study the impact of compressed data
collections from a synthetic aperture radar (SAR) sensor on the
reconstruction quality of a scene of interest. Different monostatic
and multistatic SAR measurement configurations produce differ-ent Fourier sampling patterns. These patterns reflect different
spectral and spatial diversity tradeoffs that must be made during
task planning. Compressed sensing theory argues that the mutual
coherence of the measurement probes is related to the reconstruc-tion performance of sparse domains. With this motivation, we
propose a closely relatedt%-average mutual coherence parameter
as a sensing configuration quality parameter and examine its
relationship to the reconstruction behavior of various monostatic
and ultranarrow-band multistatic configurations. We investigate
how this easily computed metric is related to SAR reconstruction
