| 英文摘要 | Optical fibre correlator comprising: - a first and a second laser diode (6, 8) emitting with the same frequency, and with an amplitude modulated respectively by a first and a second signal to be correlated; - an optical fibre (9) whose two ends are respectively coupled to the two laser diodes (6, 8) and whose length is at least equal to the length corresponding to the maximum duration of the signals to be correlated, and which comprises a flat throughout its length; - a thin layer (10) of material of noncentrally-symmetric type, applied to the flat along the whole of the fibre; - means (1 to 3) for gathering the light emitted by the layer (10) at a frequency twice the frequency of the two laser diodes (6, 8), and for delivering an electrical signal dependent on the intensity of the said light, this electrical signal conveying the correlation integral of the two signals to be correlated. The invention is applicable in the field of radar signal processing. |
