A communications system wherein there is employed a signal mixer in which a received signal is multiplied by a template signal, and then the output of the mixer is integrated. By this process, usable signals are obtained which would be otherwise obscured by noise.

대표청구항 ▼

A time domain radar system comprising: a transmitter comprising: signal generating means for generating a series of trigger signals at spaced times, a wideband transmitting antenna positioned for transmission into free space, a source of D.C. power, switching means responsive to said trigger signals and coupled to said source of D.C. potential and coupled to said transmitting antenna for abruptly switching between different states of a potential on said transmitting antenna, and transmitting a series of spaced, A.C., carrierless burst signals, each of which is generally monocyclic, into free space; and a radio receiver comprising: receiving means for receiving and providing an output responsive to wideband signals received from space between the times of transmission of said A.C. carrierless burst signals from said transmitting antenna, detection signal generating means responsive to timing signals for locally generating time spaced local signals, each local signal including a single polarity up to the duration of one polarity of a said transmitted monocyclic burst signal as received, timing means responsive to the times of transmissions of said series of said burst signals for generating, as a set, successive said timing signals and coupling them to said detection signal generating means, each said timing signal of a set occurring at a selected like time after the transmission of a said burst signal, wherein a said selected time is representative of the transit time from said transmitting antenna to a target at a selected distance and back to said receiving means, output signal mixing and integration means responsive to a said output from said receiving means and a said local burst signal for providing an output signal which is a function signal from mixing a said output of said receiving means and a local burst signal and integrating this function signal for the discrete period of said local signal, and integration means responsive to a successive set of output signals from said signal mixing and integration means responsive to a series of transmissions from said transmitting antenna, each of said last-named output signals being for an identical time of transmitted burst signal travel, for providing an integrated signal, said integrated signal being indicative of the presence of signals having been reflected from a target at a selected distance.
