| Abstract: | TSAE-Z algorithm combines time slice autocorrelation envelope detection with step-variable Zoom-FFT detection(TSAE-Z),and achieves rapid and precise detection of cyclic-stationary signals.Results of simulation shows that,on condition of the same length of data,TSAE-Z algorithm is able to significantly decrease implementing time of detection by thousand-grade,and on condition of the same implementing time,TSAE-Z algorithm can get 6dB improvement at least on detection performance as well as on detection resolution. |

| Keywords: | cyclic-stationary joint detection time slice Zoom-FFT |
