Abstract :
Efficient algorithms utilizing the Fractional Fourier Transformation (FrFT) are proposed for fast computation of the Ambiguity Function (AF) and the Wigner Distribution (WD) on arbitrary line segments. For a signal with time-bandwidth product N, the complexity of the algorithms is O(N log N)
