Abstract
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.
Claims34
A wideband transmission system comprising:
- a transmitter comprising:
- generating means for generating a plurality of time spaced signals, 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, by, (1) coherently detecting said received signals, (2) integrating, separately, a plurality of coherently detected signals, and (3) integrating the resultant plurality of integrated signals and therefrom providing intelligence signals.
