中文摘要：

将雷达系统中的相控阵理论技术应用于组合接受理论分析中,给出了理论信噪比的定义及计算方法。通过改变检波器数目、组内距和权系数等参数使各检波器接收到的地震波同相叠加,进而确定地震波能量的聚焦形态,使理论信噪比最大化。同时利用波动方程正演,验证了理论信噪比与主要组合参数之间的关系,分析了复杂地区组合接受压制噪声提高信噪比的机理,从而设计出了最优的检波器组合数目、组内距等参数,并在实际野外检波器组合地震记录中得到了验证。

英文摘要：

Phased-array control theory in radar system is used for indoor geophone arrays parameters theoretical analysis in this paper.The definition of theoretical signal-to-noise ratio（SNR）and its calculation method are presented.By changing parameters such as geophone numbers,element interval,weight coefficient etc.,seismic waves were in-phase stacked within the group to geophones and determine the energy convergence of seismic wave and the theoretical single-to-noise ratio becomes maximized.Taking advantage of the wave equation forward modeling to verify the inner relation between theoretical signal-to-noise ratio and main geophone arrays parameters,wedissect the mechanism that geophone arrays can suppress noise and improve signal-to-noise ratio in complex areas.So the best geophone arrays parameters including geophone numbers,element interval,weight coefficient are designed.And the results are verified by the actual geophone array seismic records.
