A time domain communications system wherein a broadband of time-spaced signals, essentially monocycle-like signals, are derived from applying stepped-in-amplitude signals to a broadband antenna, in this case, a reverse bicone antenna. When received, the thus transmitted signals are multiplied by a D.C. replica of each transmitted signal, and thereafter, they are, successively, short time and long time integrated to achieve detection.

[ Having thus described my invention, I claim:] [1.] A wideband transmission system comprising:generating means for generating a plurality of time spaced signals, said signals varying in time spacing at least as a function of a selected signal source, and each signal of said plurality of signals having a stepped-in-amplitude portion;transmitting means including a broad frequency band radiator responsive to said generating means for transmitting wideband, time-spaced, burst signals into a selected medium; andreceiving means responsive to wideband burst signals present in said medium, as received signals, for processing said received signals comprising:a template circuit providing template pulse signals occurring in like time spacing to that of said signal source,a coincidence, coherent, detector responsive to said received signals and said template signals for providing as an output a signal pulse when a received signal and template signal are simultaneously present,integration means responsive to outputs from said coincidence detector for providing an integral output, andintelligence output means responsive to said integration means for providing an intelligence output when said integration means has an integrated output resulting from having integrated a plurality of signal outputs from said coincidence detector.
