摘要
2008年4月至7月，利用航空重力测量系统CHAGS对某海岸地区200km×200km区域进行了重力测量。本文概述了测量情况，介绍了航空重力测量数据处理方法。数据处理结果表明，在中等湍流条件下，交叉点重力异常不符值的标准差为3．0mGal；与卫星测高反演结果相比，5’×5’格网平均重力异常的精度为4．6mGal。
Airborne gravity survey using CHAGS were flown in a 200km by 200km coast area in 2008. At first, the survey work is described than the date processing method is introduced. The results indicate that the standard derivations of the crossover errors is 3.0mGal and the accuracy of the 5 × 5 average gravity anomaly compared with the satellite altimeter derived gravity anomaly is about 4.6mGal under moderate turbulence.
