摘    要：本文根据随机过程理论,对重磁野外观测中的随机误差进行了谱估计。这种谱估计可用来估算波数域各种变换的误差传递系数K₈,从而对处理结果的精度作出恰当评价。

Abstract: The common key point of the different filter proeesses is how to make a correct spectrum estimate of the useful signals and stochastic noises. In order to estimate the error transfer of the wave-number domain transfor- mation and evaluate the reliability of the results, we also need to make a correct spectrum estimate of the stochastic noises. In this paper, we pro- posed a spectrum estimate of the stochastic errors of the magnetic and gravity observations and discussed its application in the evaluation of the reliability of the magnetic and gravity data processing.
