ICA-based technique for radiating sources estimation: application to airport surveillance

摘要

As aerial traffic becomes greater, it is more difficult to locate and recognise aircraft in the neighbourhood of civil airports. The technique proposed resorts to a particular device, monopulse radar, and to a tool called independent component analysis (ICA) to separate messages falling in the same radar beam. The algorithms used to compute the ICA use fourth-order cumulants of the observed signals.
