Abstract :
Ultra wide band (UWB) radar systems are used to get information from a detected target. This can be done by studying the shapes of incident and reflected pulses. To evaluate the target transfer function, a calibration is necessary to eliminate the influences of the system and the environment. The calibration includes deconvolution operations producing spike artifacts. In this paper a calibration approach for spike suppression by using Wiener filters in the deconvolution process is introduced
