Time domain detection and clockless logic electronic warfare receiver

摘要

A broadband radio receiver of the type usable in receiving and identifying the pulsed signals of radar transmitters in an electronic warfare environment. The receiver includes signal presence detecting apparatus in the form of a time domain signal detection apparatus usable in maintaining complex signal processing portions of the receiver, such as its fast Fourier transform generation circuit, in quiescent low energy dissipating status until needed to perform signal analysis. Such energy conservation enables use of the receiver in energy limited remote or space received environments. Energy conserving “clockless logic” or “null convention logic” is preferably used in embodying greater energy dissipating portions of the receiver.
