摘要 研究非高斯噪声中微弱瞬态信号的检测。利用静态随机共振方法对微弱信号进行处理,使瞬态信号的信噪比得到增强。在小波域建立了新的Power-Law检测器。通过仿真实验对比发现,在相同的信噪比和虚警概率下,采用提出的方法可以得到更高的检测概率。 This paper deals with the detection of weak transient signal buried in non-Gaussian noise. The undynamic stochastic resonance method is used to enhance SNR of weak signal. A novel Power-Law detector in wavelet domain is established. Simulation experiments and comparison show that, on the condition of the same SNR and false alarm rate, proposed method could provide higher detection probability.
