The author presents a summary of the ultrawideband (UWB) concept, clarifying its instantaneously large percent-bandwidth nature and the inseparability which results in its four-dimensional ambiguity function. In conventional design, this coupling is suppressed. However, evidence is presented that suggests that there may be unique performance and EMC (electromagnetic compatability) advantages to be gained from exploiting this coupling. It is explained why this improved performance is not attainable using switch-based transmitters. Attention is given to the use of a programmable function generator (e.g., a direct digital synthesizer) to generate the required UWB waveform and to the exploitation of localized wave solutions to Maxwell's equations for their contribution to improved resolution and reduced path loss
