Abstract :
Detection of soundings ultrawideband radar (UWB) signals embedded in non-stationary interference presents a difficult challenge. In this paper, analysis of synthetic signals and UWB radar data is performed using time-scale methods, such as the a discrete wavelet transform (DWT) on based Mallat´s algorithm. The performance of these methods is compared and the characteristics, advantages and drawbacks of each technique are discussed.
