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 ...
Regional Tec Mapping with Random Field Priors and Kriging
(Amer Geophysical Union, 2008)
Total Electron Content ( TEC) is an important parameter in monitoring ionospheric variability. In a given region, TEC can be obtained only by interpolation of measurements due to sparsity of the useful data. The lack of a ...
Estimation Of Single Station Interfrequency Receiver Bias Using Gps-Tec
(Amer Geophysical Union, 2008)
Dual-frequency Global Positioning System (GPS) receivers present a plausible and cost-effective way of computing Total Electron Content (TEC). For accurate estimates of TEC, frequency-dependent satellite and receiver ...
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 ...
