摘　　要：通过在多宝山地区进行的动力滑翔机航磁测量示范性工作,评价了该系统的功能和特点。根据在同一测线上不同飞行方向实测数据的对比和对平面数据的处理分析,表明资料中既无滞后现象也无方向差,说明该系统的磁三分量补偿较完善;采用重复线数据作为检查数据,通过平面内插和高度延拓,获得和检查点相同空间位置的磁场值作为被检查数据,统计的工作精度为4.0 nT。示范工作成果表明动力滑翔机航磁系统具有轻便、高效、适应性强和高精度的特点。Through the aeromagnetic survey of the power glider in Duobaoshan area,the authors evaluated the function and characteristics of the powered glider aeromagnetic system. The comparison of measured data and the processing analysis of graphic data in different flight directions on the same measuring line indicates that there is no lag and no direction difference in the data,and the three-component magnetic compensation system is relatively complete. The working accuracy is 4.0nT by using the repeated line data as the check data,the inspection data of the same spatial position with the check points can be obtained by means of interpolation and height extension. The demonstration results indicate that the powered glider aeromagnetic system has the characteristics of portability,high efficiency,high adaptability and high precision.
