| 摘 要： | 依据地质体在地面上引起磁异常的特点,提出了三方向扩边方法,这种方法能够减小边界效应,使处理结果更可靠。在实际的测量中,磁法数据受外界的干扰比较大,干扰因素给数据处理和资料解释工作带来了影响。首次将中值滤波技术引入到磁法数据处理中,提出了一种新的滤波方法,即优化中值滤波方法,来解决这个问题,并给出了优化中值滤波的模型以及计算公式。最后利用优化中值滤波方法对实际磁测数据进行处理,取得了较好的效果。

| Abstract: | Based on the characteristics of magnetic anomalies in the ground caused by subsurface geological bodies, An edge expansion method of three directions is proposed. This method can reduce the boundary effects and make the results more reliable. In the actual measurement,magnetic data is often interfered by various with factors and the factors makes the data processing and data interpretation more difficult. It is the first time that we introduce the median filtering technology to magnetic data processing, and... |
