Linear Frequency-modulated Signal Detection Algorithm Based on Fractional Fourier Transform
Abstract：According to the problem of signal detection in complex background, an improved detection algorithm is presented based on fractional Fourier transform. New method makes use of the property of relieving time-frequency coupling and power spectrum accumulation strongly. Linear frequency-modulated（LMF） signal is detected in colored noises and white Gaussian noise, simulation result shows that the detection algorithm has good detection property.
