此法以反射地震资料中的观测初至旅行时与模型射线追踪旅行时之差的最小平方法为基础。
It is based on the least square of the difference between the real reflection first break time and corresponding modeled ray-tracing travel time.
深反射地震资料处理的关键是从干扰背景中提取和增强深层弱有效信号，提高剖面的信噪比和分辨率。
The present paper has dealt systematically with a practical and effective deep reflection seismic technique—small-scale wide line reflection seismic technique.
在研究地壳结构的人工源宽角反射地震资料解释中，常规宽角反射波走时和射线路径计算大都假定地壳模型为层状块状均匀介质。
Layered and blocked homogeneous models are usually used to calculated travel times and ray paths of wide-angle reflection waves in interpreting wide-angle reflection data of deep seismic sounding.
