Abstract

A method is discussed in this paper for analysis of received ultra wideband pulse in noise based on analytical wavelet transform. Using analytical version of wavelet, the feather of the impulse shape and position can be identified from the transform results. The impulse samples can be reconstructed and have a noise reduction by employing a thresholding technology to deal with the coefficients. The echo time delay of dispersed target components can be estimated in favor of further processing of range profile of UWB-radar.
