在区域物探工作中,重磁位场的区域—剩余分离或分离区域场和局部场的问题,近几十年来,一直被推断解释人员作为一个关键的方法技术课题来研究和探讨的.40年代末至50年代,提出了徒手园滑的各种经验方法和形式不同的各种算术平均法,以及位场的高次导数法;60年代后期至70年代初,提出了所谓的“非线性滤波”法和所谓的“匹配滤波器”;此后,有人给出了一种二维最佳线性数字滤波器的设计原理(王继伦,1977);我们曾提出并在实际中应用了一种分离区域场和局部场的最小均方误差滤波器(1978),这种滤波器实质
In the area of geophysical prospecting, the area of gravity and magnetic potential fields, the remaining fields of separation or separation of fields and local fields, has been inferred and interpreted by interpreters for decades as a key methodological and technical topic to be explored and explored. From the end of 1950s to the end of the 1950s, various experience and methods of different types of arithmetic methods of landscaping were put forward, and the high-order derivative method of the field was proposed. From the late 1960s to the early 1970s, the so-called “nonlinear filtering ”Method and the so-called“ matched filter ”; thereafter a design principle for a two-dimensional best linear digital filter has been given (Wang Jilun, 1977); we have proposed and practically applied a separate field And local field minimum mean square error filter (1978), the essence of this filter
