A Technique for Obtaining D-Region Electron Density Profiles From VLF Reflection Coefficients.

reportActive / Technical Report | Accession Number: ADA050293 | Open PDF

Abstract:

A technique is described for determining D-region electron density profiles from VLF reflection coefficients. Some of the problems concerning convergence of the iterative scheme are discussed as well as the constraints introduced to account for features of the profile for which information is not provided by reflection coefficient data. Also, an example is given where the technique is applied using simulated data. Author
