Connections Among Synthetic Aperture Imaging Techniques

Inhalt:
It is common knowledge that the disciplines of synthetic aperture radar and sonar have exchanged technological advances for decades. Furthermore, both have benefited from developments in the seismic imaging community. Such advances have occurred only sporadically as researchers have become aware of cross-discipline similarities that are not always obvious. This paper surveys several key synthetic aperture imaging fields and discusses fundamental commonalities among them. In particular, we consider synthetic aperture radar and sonar, X-ray computed tomography, seismic imaging, and radio astronomy.
