ICA-based technique for radiating sources estimation: application to airport surveillance
Éric Chaumette, Pierre Comon, Dipl.Inf Volker Muller · IEE Proceedings F Radar and Signal Processing · 1993
As aerial traffic becomes greater, it is more difficult to locate and recognise aircraft in the neighbourhood of civil airports. The technique proposed here resorts to a particular device, monopulse radar, and to a recent tool called the independent component analysis (ICA) to separate messages falling in the same radar beam. The algorithms used to compute the ICA use fourthorder cumulants of the observed signals.
