On multipurpose modulations and lag profile inversion for EISCAT_3D

by Ilkka Virtanen (University of Oulu)

The lag profile inversion software developed during the E3D preparatory phase
project has been upgraded to run in a supercomputer as part of the
"HPC-approach to Ionospheric Situational Awareness (HISSA)" project funded by
the Research Council of Finland. We use synthetic voltage-level radar data to
demonstrate how the concept of multipurpose modulations may be applied to
EISCAT3D, and that lag profiles can be deconvolved from the data with
reasonable computing resources.
