摘　　要：为了量化评估航磁测量系统的动态性能指标,通常采用多次往返的重复线测量方式,来测试系统的工作稳定性和一致性,但现有规范中对重复线测量数据质量没有明确的量化标准,笔者对造成重复线磁场测量值偏差的原因进行了客观的分析,研究总结了航磁重复线测量数据均方差精度计算方法,并编写了相应的计算软件,依据重复线测量数据均方差内符合精度计算结果,客观地评估仪器的动态测量精度指标和工作状态。For the purpose of quantified evaluation of the dynamic performance index of the aeromagnetic measurement system,the back-and-forth repeated linear measurement style is usually adopted to test the working stability and consistency of the system; nevertheless,there exist no definite quantified criteria for repeated linear measurement data in the standards available. In this paper,the author made an objective analysis of the reasons for the deviation of the repeated linear magnetic field measurement data,summed up the calculation method for the mean-square deviation of the aeromagnetic repeated linear measurement data and compiled corresponding calculation software. According to the calculation results of the mean-square deviation interior coincidence precision of the repeated linear measurement data,the dynamic measurement precision index and the working condition of the instrument was evaluated objectively.
