The emerging ultra-wideband technology is in demand of extensive theoretical as well as experimental research to advance the implementation and commercial use of its numerous applications. Impulse-type signals are characterized by an ultra-wide frequency bandwidth that is desirable for the applications of high-resolution radar and wireless communications. In this paper, a signal model referred to as the generalized Gaussian pulse is derived for the analytical representation of electromagnetic impulses used in the experimentation of ultra-wideband technology. The signal characteristics of the generalized Gaussian pulse are analyzed. Computer plots of the time variation, autocorrelation function, and energy spectral density are also presented. The structure of a spread-spectrum signal for the ultra-wideband impulse technology is described too. Key-Words:-Ultra-widband signals, impulse waveforms, impulse radar, signal design
