介绍了检测和估计地震信号的Capon最大似然技术。通过采用地震台阵噪声的多维自回归近似,提出了一项用Capon的多通道滤波技术作为在线处理。结果表明,这种适用于通用噪声矩阵功率谱的自回归方法能很好地抑制互相关台阵噪声。作为一个例子,用这项技术对ARCESS台阵得到的塞米巴拉金斯克小当量地下核爆炸记录进行了检测。 The Capon Maximum Likelihood Technique for detecting and estimating seismic signals is introduced. By using multi-dimensional autoregressive approximation of seismic array noise, a multi-channel filtering technique using Capon is proposed as online processing. The results show that the autoregressive method which is applied to the general noise matrix power spectrum can well suppress the cross-correlation array noise. As an example, this technique was used to test the small equivalent of underground nuclear explosions in the Semipalatinsk acquired by the ARCESS array.
