| 中文摘要: |
| 针对水下高斯噪声中非高斯瞬态信号的检测问题,在研究Nuttall提出的power-law(幂律)检测器的基础上,为了提高其检测性能,依据信号和噪声的自相关函数的差异,提出了基于自相关函数的power-law检测器,并对其参数的最佳选取及检测性能进行了仿真研究。仿真结果表明,基于自相关函数的检测器较基于DFT的power-law检测器性能有所提高,有一定的可行性。 |
| 英文摘要: |
| For detection of underwater non-Gaussian transient signals buried in Gaussian noise,a power-law processor operating on autocorrelation function(ACF) of received signal is proposed here in order to improve the detection performance of the original detector based on DFT after a review of the latter detector.The optimum parameter for the new detector and its detection performance is studied using simulation analysis.The simulation results indicate that power-law processor based on ACF slightly outperforms that based on DFT. |
