| 摘 要： | 利用小波分析塔式算法对单一分形模型数据进行处理,结合“随机共振”理论,对高精度弱磁异常中的噪声和误差进行有效的分析评价,依据趋势分析方法获得的剩余磁异常,提出“加窗移动”最小二乘方法对应用非整数阶微积分的布郎运动正态随机行走进行控制,为高精度弱磁异常的有效识别提供有益的指导。

| Abstract: | This paper processed the simple fractal data with pyramidal algorithm of wavelet analysis and, in combination with the "random resonance" theory, analyzed and approached noise and error in high-precision micro-magnetic anomaly. According to residual magnetic anomaly detected by tendency analysis, the authors suggest controlling normal random Brown motion of non-integer rank calculus with "shift with the window" least squares technique, and provide essential guidance for effective recognition of high-precision micro-magnetic anomaly. |
