Patent ID: RE41479

Claim:
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; and receiving 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, and intelligence 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.
