| 摘 要： | 在最小二乘逐步配置基础上，提出了以调整观测信号自协方差及互协方差函数为主要形式的多源重力数据自适应融合处理方法，构建了基于配置结果的自适应融合以及基于观测信号的自适应融合两种融合模式。分别利用两种融合模式对渤海湾陆海交界区域的航空重力数据、卫星测高反演重力数据以及陆地重力数据进行了融合处理，其中基于观测信号的自适应融合模式取得了较优的融合效果，通过船测重力数据的外部检核表明，融合数据的总体精度优于3.7毫伽 。 |

| Abstract: | Based on the least square stepwise collocation,the adaptive fusion method is presented which has two fusion modes including the mode based on the traditional stepwise collocation and the mode based on the new recursion collocation.The airborne gravity data,satellite altimetry gravity data and land gravity data are fused by using the two fusion modes.The computation results show that the fusion based on recursion collocation has better accuracy and reliability than the other modes.According to the extra-veri... |
