ABSTRACT:
A modulated ultra wideband pulse generation system is provided. The system comprises a pulse waveform generator circuit operable to generate an on-off pulse waveform, and a modulating circuit operable to receive a modulating signal and to modulate the on-off pulse waveform in response to the modulating signal. Further embodiments of the invention comprise a variable bandwidth circuit operable to alter the bandwidth of the pulses comprising the on-off pulse waveform. Various embodiments of the invention comprise on-off keying modulation, pulse position modulation, and pulse phase modulation.
