Compressive receiver










Image Number 2 for United States Patent #4305159.

The envelope detector of a compressive receiver is replaced with either a Fourier Transform device or a demodulator such that the output of the dispersive delay line utilized in the receiver is processed to yield the spectrum of the incoming signals and/or the modulation impressed on the incoming signals, thus to permit rapid identification of a signal and its source. In order to permit spectral analysis and/or demodulation of many signals over wide bandwidths, an especially wide bandwidth dispersive delay line is utilized along with a sweep-to-sweep phase coherent variable frequency oscillator.
