IF-77 Air-to-Ground Propagation Model (Gierhart-Johnson)
The Irregular Lunar Model
ITS Irregular Terrain Model (ITM), which predicts terrestrial radiowave propagation for frequencies between 20 MHz and 20 GHz based on electromagnetic theory and empirical models developed by Anita Longley and Phil Rice.
NTIA/ITS C++ implementation of Low Frequency / Medium Frequency (LF/MF) Propagation Model. The LF/MF model predicts basic transmission loss in the frequency range 0.01 - 30 MHz for propagation paths over a smooth Earth and antenna heights less than 50 meters.
Python wrapper for the NTIA/ITS implementation of the Low Frequency / Medium Frequency (LF/MF) Propagation Model. LF/MF predicts basic transmission loss in the frequency range 0.01 - 30 MHz for propagation paths over a smooth Earth and antenna heights less than 50 meters.
This repository contains a dataset used to test the NTIA/ITS implementations of the Low Frequency / Medium Frequency (LF/MF) Propagation Model.
Open software framework for collaborative development of no reference image and video quality metrics
NTIA/ITS implementation of Recommendation ITU-R P.2108. This Recommendation contains three methods for the prediction of clutter loss: the Height Gain Terminal Correction Model, the Terrestrial Statistical Model, and the Aeronautical Statistical Model.
Python wrapper for U.S. Reference Software Implementation of Recommendation ITU-R P.2108
This repository contains a dataset used to test the NTIA/ITS implementations of Recommendation ITU-R P.2108.
