摘要： A method is provided for performing real-time spectral analysis of a non-stationary signal. The method includes sampling the non-stationary signal, using an observation window having a length short enough to approximate a stationary signal, to provide an initial set of sampled data, buffering the initial set of sampled data to obtain multiple buffered sets of sampled data, filtering the initial set of sampled data and the buffered sets of sampled data, using corresponding filter responses, to obtain multiple filtered sets of sampled data, and performing a chirp-z-transform (CZT) of the filtered sets of sampled data to provide a set of discrete Fourier transforms (DFT) coefficients. A total signal spectrum of the non-stationary signal is reconstructed using the set of DFT coefficients.

摘要： An electro-optic delay line frequency discriminator has an optical signal source providing first and second optical signals that are directed along first and second paths, respectively. In the first path, the first optical signal is converted to a first corresponding optical signal that corresponds to an electrical input signal, and the first corresponding optical signal is then delayed. In the second path, the second optical signal is delayed, and the delayed second optical signal is then converted to a second corresponding optical signal that corresponds to the electrical input signal. The first and second corresponding optical signals are converted to first and second corresponding electrical signals, respectively; and a detector, responsive to the first and second corresponding electrical signals, provides an electrical output signal from the discriminator. Optical source relative intensity noise (RIN) is canceled out and does not degrade the signal-to-noise ratio of the discriminator output.

摘要： A method and apparatus for performing simultaneous instantaneous signal frequency measurement using a signal sorter in conjunction with a frequency measurement receiver. Simultaneous signals of similar amplitude are received and successively applied to a plurality of either frequency or time dependent signal modifying circuits, via switching circuitry. Respective ones of the received signals are separated with respect to frequency in one or both of amplitude and time from one another via the signal modifying circuits which can be, for instance low pass and high pass filters, or positive and negative dispersive delay lines. In addition, the received signals are applied to a straight-through signal path for transmitting the signals to the frequency measurement receiver unaltered. Signals output from the signal modifying circuits and the straight-through signal path are successively applied to the frequency measurement receiver for detecting the frequency of respective ones of the separated received signals.

摘要： A continuous wave laser and modulator drives a fibre optic delay line whose output is detected by a photo detector and gain control amplifier. The signal from the amplifier is phase advanced in a modulator by a phase advance signal whose period is equal to the loop delay including the delay line. The resulting signal is added to an input signal in an adder whose output is the modulating signal for the modulator. Cycles of the phase advanced signal are counted to establish a processing time of N circulations round the loop where N might be 160 or significantly larger. At the end of the processing time, the output signal from the adder, over a segment equal to the delay time, represents the frequency spectrum of the input signal. N can be varied to vary the resolution of the measurement. The fibre optic delay line provides a highly stable determinate delay and permits very wide band operation.

摘要： The present invention relates to a method (50) for detecting a plurality of useful signals in a total signal. Said useful signals correspond to radioelectrical signals emitted by different terminals in a multiplexing frequency band. Said method comprises steps for: - calculating (51) a plurality of spectrograms that have a compensated linear frequency drift and are respectively associated with different linear frequency drift values; and for each analysis frequency and each spectrogram, - performing time envelope filtering (52) of the values at the different times for analyzing said spectrogram at said analysis frequency by means of a filter representing a reference time envelope of the useful signals. A useful signal is detected at an analysis time and at an analysis frequency if a predefined detection criterion is verified by the value from a spectrogram resulting from filtering, that is, a so-called "filtered spectrogram," for said analysis time and said analysis frequency.

摘要： Un récepteur à large bande passante servant à convertir un signal d'entrée de haute fréquence (36) en des impulsions de sortie (50) produit l'expansion de la largeur d'une impulsion de sortie (50) pour permettre le traitement des impulsions à l'aide d'un équipement conventionnel à des cadences de traitement plus lentes. Un oscillateur local de balayage (42) module en fréquence le signal d'entrée (36) pour créer un signal modulé en fréquence qui est comprimé en une impulsion par une ligne de retard à dispersion (40). La largeur de l'impulsion de sortie (50) est augmentée en produisant une non-correspondance ou différence dans les pentes fréquence/temps (52, 54) de l'oscillateur et de la ligne de retard à dispersion. La différence de pente est obtenue à l'aide d'un générateur de fonction (58, 68) qui maintient la pente fréquence/temps (52) de l'oscillateur local de balayage (42) à une valeur différente de celle produite par la ligne de retard à dispersion (40).
