与面积组合等效的检波器线性组合方法

LINEAR GEOPHONE ARRAY WITH NEARLY THE SAME EFFECTIVENESS OF THE AREAL ONES

本文根据组合检波器方向性效应的原理,提出了用线性组合代替面积组合的设想。这一方法的野外实施十分简便易行。从理论上讲,它可以压制沿表层传播的不同方向的干扰。特别是当室内资料处理采用道间组合时,效果将更为理想。

It is possible to anticipate that an areal geophone array could be taken over by linear ones under the condition of the directional characteristics remain unchanged. Apart from the facility and simplicity of the field equipment for linear ones, the interference waves propagating along the surface with different directions may even be suppressed by means of linear geophone array theoritically . Particularly, more excellent results could be expected in case that channel combination is used for indoor data processing.
