METHOD AND DEVICE FOR GENERATING ULTRA WIDE BAND PULSES (UWB)

摘要

The invention relates to a method of generating UWB waveforms each comprising a sequence of elementary pulses, the method comprising steps consisting in: generating at least two pulse signals (E1, E2) each comprising a train of elementary pulses (e1, e2,...) substantially of the same amplitude and of duration corresponding to a setpoint duration, the elementary pulses appearing alternately in the two pulse trains, for each pulse signal, generating an amplitude signal (V1, V2) indicating for each elementary pulse and upon its appearance in the pulse signal an amplitude setpoint (Va1, Va2,...) of the elementary pulse, combining the pulse signals and the amplitude signals to obtain a waveform (s) successively comprising each of the amplified elementary pulses, and alternately positive and negative, the elementary pulses being amplified in accordance with the amplitude setpoint of the elementary pulse, provided by one of the amplitude signals.
