| 摘 要： | 基准图制备是地磁匹配制导的关键技术之一。提出用总磁场强度梯度模作为地磁匹配特征量,根据研究的实际需要,从四个方面分析了地磁场梯度模作为匹配特征量的优势;在选定区域制作了以总磁场强度梯度模作为特征量的基准图,在基准图上提取了特征参数并进行了分析。结果表明:在选定区域,以总磁场强度梯度模作为特征量生成的基准图特征丰富、起伏程度大,较之以地磁总场强度为特征量生成的基准图优势明显。

| Abstract: | According to the actual requirements,the advantage of total geomagnetic intensity gradient amplitude used as matching feature is analyzed in four aspects.The reference map of selected area is produced with the total geomagnetic intensity gradient amplitude matching feature.The matching feature parameter of the map is extracted and analyzed.The results indicates that the reference map produced is more advanced with abundant feature,large variation range and high matching probability than that produced with the total magnetism intensity as matching feature. |
