  1. Hans Hellsten and Lars E. Andersson. An inverse method for the processing of synthetic aperture radar data. Inverse Problems, 3(1):111-124, 1987.
    Keywords: SAR Processing, Backprojection, Hankel Transform, Fourier-Hankel Inversion, Abel Transform.
    Abstract: An inverse method for the processing of synthetic aperture radar signals is presented. The method is independent of the relative bandwidth of the radar signal and should thus work when, for instance, the frequency of the emitted radiation is of the same order as the bandwidth, i.e. in low frequency, high resolution applications. It is shown that the obtained relations reduce to the correlation integrals of conventional SAR image processing in the case that the relative bandwidth of the signal is small. Range attenuation and antenna illumination effects may be fully compensated for.

  2. Fabio Rocca. Synthetic Aperture Radar: a New Application for Wave Equation Techniques. Stanford Exploration Project SEP-56, pp 167-189, 1987.
    Keywords: SAR Processing, Range Migration Algorithm, omega-k, Wavenumber Domain Algorithm, Seismic Migration Techniques.
    Abstract: The techniques of downward continuation and imaging invented for seismic waves can be applied to other types of waves. In this paper, we see how this application can be made in the case of 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. In the case that we analyze in detail, a survey carried out using a satellite, difficulties arise from the fact that the orbit of the satellite cannot be approximated with a simple straight line if the spatial resolution of the survey is high. We determine appropriate techniques for the correction of the distortion induced by the latter and we delimit the resolution of the observed data, as seen from a satellite. Finally we show examples of the application of the technique of seismic migration to satellite data that were irradiated to earth during the short but productive life of SEASAT.

This collection of SAR literature is far from being complete.
It is rather a collection of papers which I store in my literature data base. Hence, the list of publications under PUBLICATIONS OF AUTHOR'S NAME should NOT be mistaken for a complete bibliography of that author.
