A comparative study of NN and SVM-based electromagnetic inverse scattering approaches for on-line detection of buried objects

Microwave-based sensing techniques constitute an important tool for the detection of buried targets. In this framework, a key issue is represented by realtime scatterer localization. As far as such a topic is concerned, this paper presents a comparative evaluation of the performances provided by a conventional NN-based inverse scattering technique and by a new SVM-based electromagnetic approach. In order to estimate the effectiveness values of the two methods, realistic configurations and noisy environments are considered and current capabilities, as well as potential limitations, are pointed out. Finally, possible future research work is outlined.
