This article describes the development of experimental work on ionospheric tomography carried out in Europe. It starts with early two-station observations and discusses the recent complex coordinated campaigns that have involved ionosondes to determine the bottomside profile and incoherent scatter r

โฆ Synopsis
One of the most recent applications for tomographic imaging is the measurement of the electron density distribution in the ionosphere. This imaging system is a unique and challenging tomographic system because of the physical constraints of the system and the nature of the electron density distribution. To fully understand the potential and limitations of this imaging system, analysis of the resolving capabilities is needed. This article provides a review of current analysis methods for both system evaluation and characterization of the effects of individual degradation parameters. This article also presents a study of the effect of system configuration on the information content of projections.

Traditionally, knowledge of the ionospheric electron density is obtained using Faraday rotation or differential Doppler techniques which measure total electron content in columns of the ionosphere. Conventional data processing can only image the electron density in the direction perpendicular to the
The estimation of transmitter location based on radio frequency reception at a single site has long been a challenge. The standard technique for location estimation has typically used an active local vertical transmitter (ionosonde) to characterize the local ionosphere for propagation path modeling.
