| 摘 要： | 对于高精度航空磁测来说,飞机磁干扰必须有效的消除,其方法是补偿飞行。补偿效果的好坏直接影响到物探飞行数据的质量,所以有必要采用一些量化指标对磁补偿的效果进行评价,从而对补偿飞行的质量进行有效地控制。这里介绍了飞机磁干扰场的补偿原理及两种评价补偿效果的指标:品质因数(FOM值)和标准差(σc),采用了这两个量化指标对磁补偿的效果进行评价,就能对补偿飞行的质量进行有效的控制。

| Abstract: | For high accuracy aeromagnetic survey,the magnetic interference of aircraft must be effectively eliminated,which is compensation flight.The effect of compensation has a direct influence on the flight data quality of geophysical exploration.This paper introduces the compensation principle of aeromagnetic and two indexes to evaluate compensation result：figure of merit （ FOM value ）and standard deviation （σc）.This is very beneficial to control the quality of the compensation flight,adopting these two quantitative index to evaluate the result of magnetic ompensation.Hope and discussed together. |
