重磁异常信号的非高斯性探讨

The discussion on the non Gauss of gravity and magnetic anomalies signals

从盲源分离方法的问题及假设条件出发,阐述了探讨重磁信号非高斯性的必要性;通过对不同理论模型重磁异常信号的非高斯性进行研究,得出球体与直立长方体的重磁异常信号不是高斯信号;同时得出台阶重磁异常信号的非高斯性与其埋深有关,与磁化方向无关。

Firstly,the paper proposed the necessity of discussing the non Gauss of gravity and magnetic anomalies signals according to the basic assumptions of the blind source separation and separation conditions.Secondly,it was obtained that gravity and magnetic anomaly signals of the sphere and upright rectangular are not Gauss signals by studying on the Gauss of gravity and magnetic anomalies signals of the different theoretical models.At the same time,it was concluded that whether the gravity and magnetic anomalies of steps is Gauss signals,depends on its depth rather than the direction of magnetization.
