1. A UWB pulse emitter comprising:
at least one H-bridge, said at least one H-bridge having a first branch and a second branch in parallel, a first end common to the first and second branches being connected to a high voltage and a second end common to the first and second branches being connected to a low voltage, the first branch comprising a first midpoint and the second branch comprising a second midpoint, a UWB antenna being connected to the first midpoint and/or to the second midpoint, the first branch comprising a first switch between said first common end and the first midpoint as well as a second switch between the first midpoint and the second common end, the second branch comprising a first switch between said first common end and the second midpoint as well as a second switch between the second midpoint and the second common end, the first and second switches of a branch being in opposite switching states and the switching state of the first switch of the first branch being opposite to the switching state of the first switch of the second branch, each switch being switched at the same RF frequency giving the central frequency of the UWB pulses;
a first amplitude control module between a power supply terminal and the first common end, allowing varying said high voltage at the first common end, and/or a second amplitude control module between the second common end and the ground, allowing varying said low voltage at the second common end;
a first envelope control module between the first switches and the midpoints of the two branches, intended to shape the envelope of the positive part of a UWB pulse by means of a first baseband signal; and
a second envelope control module between the midpoints and the second switches of the two branches, intended to shape the envelope of the negative part of a UWB pulse by means of a second baseband signal.
