Investigation of Total Electron Content Variability Due to Seismic and Geomagnetic Disturbances in the Lonosphere
(Amer Geophysical Union, 2010)
Variations in solar, geomagnetic, and seismic activity can cause deviations in the ionospheric plasma that can be detected as disturbances in both natural and man-made signals. Total electron content (TEC) is an efficient ...
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 ...
Association of Ionospheric Storms and Substorms of Global Electron Content with Proxy Ae Index
(Elsevier Sci Ltd, 2015)
Storm time modeling of Global Electron Content (GEC) calculated from GIM-TEC for 1999-2013 is associated with new proxy of Auroral Electrojet variability expressed as a smoothed and normalized Auroral Electrojet index ...
A New Technique for Direction of Arrival Estimation for Ionospheric Multipath Channels
(Elsevier Sci Ltd, 2009)
A novel array signal processing technique is proposed to estimate HF channel parameters including number of paths, their respective direction of arrivals (DOA), delays, Doppler shifts and amplitudes. The proposed technique ...
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 ...
