SYNTHETIC APERTURE RADAR:A NEW APPLICATION FOR WAVE EQUATION TECHNIQUES1

Abstract: The techniques of downward continuation and imaging invented for seismic waves can be applied to other types of waves. We show how they can be applied to electromagnetic surveys conducted with Synthetic Aperture Radar (SAR). The algorithms used closely follow those used for seismic waves. Differences are induced by alternate wavelengths, wave velocities, distances between sources and reflectors, etc. We analyse in detail a survey carried out using a satellite; difficulties arise from because the orbit of the s… Show more

“…----_ the field of seismic signal processing for imaging the Earth's substrata, as described in [14] and [1.5],and was originally applied only to stripmap SAR collections. Subsequent papers by Prati, et al, demonstrate the extension of RMA as it applies to spotlight-mode processing [16,17], and it was thought to be the logical successor to polar-format processing due to its inherent ability to compensate for wavefront curvature.…”

“…Image creation can be performed in the image (or time) domain or in the frequency domain. Some of the most important frequency domain methods are the Range-Doppler (Walker, 1980), the Fourier-Hankel (Fawcett, 1985;Hellsten and Andersson, 1987;Andersson, 1988) and the ω-K migration methods (Rocca, 1987;Cafforio et al, 1991;Milman, 1993). The frequency domain methods are generally fast, but has a downside that they assume straight trajectories in order to work properly.…”
