Method and apparatus for detecting amplitudes and/or phases of recognizable signals in a frequency band or spectrum of interest

摘要

A method of and apparatus for detecting signal features including amplitude, phase and timing of recognizable input signals in a frequency band or spectrum of interest. One or more super-regenerative oscillators are provided, each having a center frequency and each detecting signal features of recognizable input signals in the frequency band or spectrum of interest during multiple, successive time slots. The center frequency of each of the one or more super-regenerative oscillators is varied between time slots in a selected sequence, preferably according to a Segmentlet algorithm. The one or more super-regenerative oscillators extract the signal features of each the recognizable input signals in different time slots and/or in different super-regenerative oscillator and with a different time-slot associated center frequency associated with the one or more super-regenerative oscillators, thereby providing a time-frequency-amplitude map of the frequency band or spectrum of interest.
