摘要
提出一种新的数据处理方法———子区中位数衬值滤波法。该法采用子区模拟背景场的空间变异，以ＥＤＡ技术计算异常临界值，用衬值为基准度量场值的起伏变化，较好地解决了弱小异常的识别问题。初步应用效果良好。
This paper advances a new data processing technique subregion median contrast filtrering method.It uses subregion to simulate spatial variation of the background, calculates critical values of anomalies with EDA technique, and measures the undulation of field values with the contrast as the datum. This technique fairly satisfactorily solves the problem of recognizing weak anomalies, and the preliminary application proves it to be effective.
