The time-delay reflection spectrum of fiber Bragg gratings (including both uniform and non-uniform FBGs) serves as a valuable tool in optical sensing applications, enabling precise parameter detection through spectral analysis algorithms.
This implementation utilizes a uniform linear array structure and employs fourth-order cumulants to generate virtual array elements, enabling the estimation of more signal sources than physical array elements for Direction of Arrival (DOA) estimation. The method achieves superior resolution through virtual array expansion and can be implemented using MATLAB's signal processing and statistics toolboxes for cumulant calculation and spatial spectrum estimation.
In constant false alarm rate detection technology, the traditional OS-CFAR method provides a robust approach that can theoretically derive detection probabilities with mathematical formulas across homogeneous environments, clutter edges, and multiple interfering targets. This implementation demonstrates MATLAB simulations of OS-CFAR performance under various scenarios, featuring algorithm implementation details including reference cell sorting, rank selection, and threshold calculation mechanisms.
