Theory of Daylight/Interferometric Imaging: Tutorial

Interferometric Seismic Imaging

Claerbout’s daylight imaging concept is generalized to the general theory of interferometric seismic imaging (II). Interferometric seismic imaging is defined to be any algorithm that inverts crosscorrelated seismic data for the reflectivity or source distribution. As examples, we show that II can be used to image reflectivity distributions by migrating ghost reflections in passive seismic data,...

Theory of acoustic daylight imaging revisited

Interferometric array imaging in clutter

We introduce a space-time interferometric array imaging functional that provides statistically stable images in cluttered environments. We also present a resolution theory for this imaging functional that relates the space-time coherence of the data to the range and cross-range resolution of the image. Extensive numerical simulations illustrate the theory and address some implementation issues....

Optical Physics of Imaging and Interferometric Phased Arrays

Microwave, submillimetre-wave, and far-infrared phased arrays are of considerable importance for astronomy. We consider the behaviour imaging phased arrays and interferometric phased arrays from a functional perspective. It is shown that the average powers, field correlations, power fluctuations, and correlations between power fluctuations at the output ports of an imaging or interferometric ph...
