本文提出了一种有效的方法来检测被非平稳随机噪声污染的信号。首先，由于噪声的统计特性是非平稳的噪声观测数据进行修改，使它们成为平稳的。然后，基于该平稳化观测处理，执行平稳性测试以检测信号。仿真结果表明了该方法的有效性
In this paper, an effective method is proposed for detecting a signal which is corrupted by nonstationary random noise. First, the noisy observation data whose statistical property is nonstationary owing to the noise is modified such that they become stationary ones. Then, based on this stationarized observation process, the stationarity test is executed to detect the signal. The method is tested by simulations to show the efficacy
