Abstract :
Artificial neural networks are highly suited to the application of data fusion. This paper presents a range of multilayer feedforward network structures designed to perform parameter extraction from simulated ionograms. The experimental results show an eightfold improvement on nondata fusion techniques, and also allow for the extraction of gradient information. This demonstrates the ability of data fusion to improve the accuracy of a system, and to produce information that would otherwise be unavailable
