FRFT Source Code and LFM Signal Detection Implementation

Two MATLAB programs are provided: one implements the Fractional Fourier Transform (FRFT) algorithm, while the other applies FRFT for linear frequency modulation (LFM) signal detection. The core algorithm performs fractional Fourier transforms with varying orders (different fractional domains) on observed signals, creating a 2D energy distribution in the time-frequency plane. By conducting threshold-based 2D peak search on this distribution, the method detects LFM signals and estimates their parameters through峰值 analysis and parameter extraction techniques.
