摘要: |
TSAE-Z算法把时间切片自相关包络检测和可变步进的Zoom-FFT检测相结合,实现了对循环平稳信号的快速、精确检测,仿真结果表明,在相同数据长度条件下,TSAE-Z算法能够使检测运算时间减少3个数量级;在相同执行时间的条件下,TSAE-Z算法能在提高检测分辨率的同时使检测性能提升6dB以上。 |

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 |
