An Improved Target Detection Algorithm Based on Fractional Fourier Transform
Abstract：Traditional signal detection and noise separation methods are restricted in time domain or frequency domain, but the results will not be nice if the signal and noise are coupled intensely. An improved Fractional Fourier transform detection algorithm is presented for this problem. New algorithm can get rid of the coupling and reduce the noise. A preferable detection result will be got in fractional Fourier domain if a suitable rotation angle is adopted to match with the processing signal. Moving target detection is simulated, result shows that the performance of new method detection is better than fractional Fourier transform algorithm.
