而精确预测无线电波传播路径损耗特性，则为合理的微蜂窝无线网络规划、设计提供了必要条件，同时也是研究微蜂窝移动通信系统性能的前提。无线电波传播预测的方法分为两类：一是用冲激响应法，即根据实验、统计所得数据建立经验性传播预测模型；另一种是用射线跟踪方法，即依据理论分析来建立确定性的传播预测模型。本文首先讨论了在地球表面均匀大气中的无线电波传播的基本特性，介绍了陆地移动通信系统中常用的几种电波传播路径损耗经验性预测模型，并指出了这些经验性传播模型对于微蜂窝小区无线电波传播特性研究的局限性。 - For processing of 3d and 3c seismic data , the reflected p - waves can be processed with the conventional methods , while the reflected converted waves can not be processed with the conventional p - wave processing methods , because their travel paths are asymmetrical , their common midpoint gathers are no longer common reflection point gathers , and their time - distance equation is non hyperbolic
在三维三分量地震勘探资料处理中，对于反射纵波资料可以采用常规方法进行处理；而对于反射转换波资料，由于其传播路径的非对称性，转换波共中心道集不再是共反射点道集，转换波时距方程也不是双曲方程，因此不能采用常规纵波处理方法来处理转换波资料。 - This paper presents the prestack time migration to curved rays for minor fault blocks , which is of more accurate migration , allowing the travel - time equation to be more close to the real pathway of layered media seismic wave propagation , the focused imaging to be more precise , the migrated results to be of good preserved amplitude processing property and the output trace gathers to be used for the lithologic analysis and inversion study
