| Abstract: | The changes in phase path. ΔP, and group path, ΔP′, of a fixed frequency CW transmission were obtained over a ground range of ≈ 120 km. During the passage of TIDs through the ray path, changes in phase of 180° between ΔP and ΔP′ were found to occur over several cycles. A simple model incorporating moving triangular irregularities superimposed on a linear background electron density profile was used to calculate ΔP and ΔP′, and using this model, phase shifts between ΔP and ΔP′ were found which were similar to those encountered experimentally. |
