| 摘 要： | 在地震资料采集过程中,检波器除接收有效信号外,也接收了某些类型的干扰波.为了压制干扰波,突出有效波,一般要进行检波器组合.组合检波主要利用有效波和干扰波在传播方向、视速度上的差异来提高地震资料的信噪比.介绍了检波器简单线性组合和切比雪夫加权组合的基本原理,比较分析了两种组合的差异.检波器简单线性组合相当于低通滤波,随N...

| Abstract: | The effective signal geophones could receive some types of interference waves in seismic data acquisition.Geophone array was generally used to suppress the interference waves and predominate effective waves.The difference of the direction of propagation and apparent velocity between the effective waves and interference waves was used to improve the signal-noise ratio.The basic principles of conventional and linear geophone array and Chebyshev geophone array are introduced,and the difference between them is ... |
