本文依据最优化列阵滤波的基本理论,对二种具有一般意义的记录模型,提出了新的处理方法,给出了相应的理论推导。本文中还介绍了自行研制的最优化列阵滤波应用模块,分析了这种滤波在压制线性噪声(以浅层折射为例)和分离VSP波场应用过程中的成果和特点。

In line with the basic theory of optimal array filtering, a new processing techigue and its corresponding theoretical deduction for two common record modes were given. The application module for optimal array filtering , the achievements in linear noise suppression and in VSP wave-field separation were introduced and examined.
