Analysis of the Effects from Equatorial Plasma Bubbles Detected by the C-NOFS Planar Langmuir Probe on the Propagation of Transionospheric Wideband Signals
Abstract
An observational campaign of transionospheric wideband UHF (360 380 MHz) signal transmission was performed at Ascension Island in October 2016. Different effects from the low latitude ionosphere were observed. Based on the recorded data, the mitigation of adverse propagation effects using an array of four spaced receivers in the east west direction was also analyzed. The objective of the proposed work is to investigate how the large scale equatorial plasma bubbles, alone or in combination with the small scale ion density irregularities that populate them, affect the propagation of transionospheric wideband signals in low latitude and equatorial regions. The proposed work will be performed by the application of radio wave propagation models (based on the numerical solution of a parabolic equation and ray tracing) to data recorded by the Planar Langmuir Probe onboard the Communication-Navigation Outage Forecasting System satellite. Results will be compared with those from the experimental campaign.
