A New Algorithm for High-Quality Ionogram Generation and Analysis
(Amer Geophysical Union, 2002)
Standard digital ionograms that are generated by fast Fourier transform or autoregressive modeling suffer from high interference levels due to other users of the HF channel which produce artifacts and distortion, hence ...
Mode Separation And Direction Of Arrival Estimation In Hf Links
(Amer Geophysical Union, 2003)
[1] Estimation of arrival angles and incoming signals is a challenging problem for HF channels where the signals are correlated and the separation between the signals can be as low as a couple of degrees. In this paper, a ...
Regularized Estimation of Vertical Total Electron Content From Gps Data For A Desired Time Period
(Amer Geophysical Union, 2004)
In this paper a new algorithm for short-term regularized estimation of vertical total electron content (VTEC) from Global Positioning System (GPS) data is developed. The regularization technique can combine signals, from ...
