    Area of Science:

    • Photonics and Optics
    • Signal Processing
    • Artificial Intelligence

    Background:

    • Transient stimulated Brillouin scattering (SBS) with optical chirp chain (OCC) technology offers high temporal resolution for microwave frequency identification.
    • Increasing the OCC chirp rate expands instantaneous bandwidth but leads to spectral asymmetry, reducing traditional demodulation accuracy.
    • Existing methods struggle with accuracy when dealing with high chirp rates in transient SBS spectra.

    Purpose of the Study:

    • To enhance the accuracy and efficiency of microwave frequency identification using transient SBS and OCC technology.
    • To overcome the limitations of traditional fitting methods in demodulating asymmetric transient Brillouin spectra caused by high chirp rates.
    • To develop a high-performance measurement scheme for real-time microwave tracking.

    Main Methods:

    • Implementation of a microwave frequency measurement scheme utilizing optical chirp chain (OCC) technology.
    • Application of advanced algorithms, including image processing and artificial neural networks, for spectral analysis.
    • Employing matrix computations for efficient data processing and demodulation.

    Main Results:

    • Achieved a 4 GHz instantaneous bandwidth with 100 ns temporal resolution.
    • Improved demodulation accuracy from 9.85 MHz to 1.17 MHz for transient Brillouin spectra under a 50 MHz/ns chirp rate.
    • Reduced time consumption by two orders of magnitude compared to traditional fitting methods due to matrix computations.

    Conclusions:

    • Advanced algorithms significantly enhance the accuracy and efficiency of OCC transient SBS-based microwave measurements.
    • The proposed method enables high-performance, real-time microwave tracking.
    • This research opens new possibilities for diverse application fields requiring precise microwave analysis.
