SHARAD Open Focusing Attempt

SOFA - SHARAD Open Focusing Attempt

SOFA is an experimental focuser for SHAllow RADar (SHARAD) radargrams written in python v3.

The focusing algorithm is inspired by the one developed and described by the U.S. SHARAD Science Team on the PDS Geosciences Node website (http://pds-geosciences.wustl.edu/mro/mro-m-sharad-5-radargram-v1/mrosh_2001/document/rgram_processing.pdf). SOFA algorithm extends those concepts by allowing the focusing of the radargram using a squint angle different from zero (i.e., squinted focusing), by using proper phase shifting. Ionosphere effect compensation has not been implemented yet.

Using this focuser it is possible to obtain new SHARAD products with possible better characteristics than those usually published on the PDS. Some applications are better documented on http://af-projects.it and the related code is available on this same repository.

NOTE: This project has not been developed during my work at the University of Trento, nor it has been supported by the University of Trento in any way.

Want to host SOFA?

If you wish to host SOFA on your web server to provide an online radar sounder focusing didactic tool, contact me on www.af-projects.it and we may collaborate!
