The fringes are caused by topography.
The effective baseline is approximately 1100 meters.
The Doppler centroid frequency was around -8500 Hz for both images.
The processed area is ca. 100 x 30 km.
What we want to show here is that Doris is able of reading the RADARSAT images, and can process it. Unclear is still whether all modules that have been implemented for ERS also can be used for RADARSAT processing. We hope that the experience of users with this new ability of Doris can help to develop it further.
Main problem areas are the accuracy and time of the orbital data and the
reference system they are given in.
Furthermore, the absence of yaw steering and associated possible
large Doppler centroid frequencies,
and other filters used (compared to ERS SLC data).
However, this image proofs that Doris software is able to process the data, and we welcome people to tell us their experiences. For example on which multilooking factors for the interferogram generation they used, what parameters to use during spectral filtering, how the automated co-registration process went, etc. We hope that people that need to create a RADARSAT interferogram can at least create an initial interferogram with the provided modules. For improvement then we hope people can extend these routines themselves, or in co-operation with us.
As always, we encourage you to use the Doris logo in your presentations, and to include a reference to the fringe paper in your publications, stating that you used the Doris software for your interferometric processsing.
For reference we provide the
of Doris during processing of the RADARSAT SLC data.
