1. A process for generating electrical pulse signals for transmitting an electrical pulsed signal of an ultra wideband type,
the process comprising:
generating successive groups of N bits at a frequency Fe greater than a predetermined frequency PRF, at least one of the successive
groups comprising at least one subgroup of at least one bit defining at least one digital cue of position and of shape of
at least one base pulse within a window of length 1/PRF, with N being an integer greater than or equal to 2;
converting the at least one digital cue of position and of shape into the at least one base pulse;
filtering the at least one base pulse using at least one high-pass filter for providing a filtered electrical pulse signal
of the ultra wideband type positioned within the window with a temporal accuracy equal to 1/N*Fe.
