Abstract

Proposes a time-frequency analysis of Ascans signals provided by a ground penetrating radar in order to detect and to find mines signatures. Two analyses are proposed. The first one deals with the detection of buried objects by determining the time-frequency distribution maxima. The time-frequency distribution is computed using a fast Fourier transform on the windowed signal. A second type of analysis is also proposed. It is based on natural resonance frequencies and a TLS-Prony estimation of these frequencies
