摘要 

匹配滤波技术分离深源场和浅源场的方法已广泛应用于重磁资料处理.本文根据格林等效层原理,设计多层格林等效源层模型,对径向平均对数功率谱进行精细线性拟合,从而实现深源场和浅源场的分离.理论模型和实际资料对比分析表明该方法简单、实用、对大面积的航空重力能快速有效的分离深源场和浅源场,在研究区域重力异常特征、深部构造特征、划分大地构造单元、确定断裂带和地质构造走向等方面提供了重要的参考依据.

Abstract

The application of the matched filtering technology to the separation of the deep source field from the shallow source field has been widely used in the processing of gravity and magnetic data. Based on Green's equivalent layer principle, the authors designed a multi-layer Green's equivalent layer model, and then performed fine linear fitting for radial average logarithmic power spectrum, thus realizing the separation of the deep source field from the shallow source field. The comparative analysis of the theoretical model and the practical data shows that this method is simple and practical. It can separate the deep source field from the shallow source field rapidly and effectively in large-area aerial gravity measurement, and can provide important reference basis for the study of the gravity anomaly characteristics and deep structure features, the division of geotectonic units and the determination of the strike of the faulted zone and the geological structure.
