Common Reflection Surface stack is a brand-new and special ZO imaging method, the theory of CRS stack stems from paraxial ray theory, the biggest difference between CRS stack and conventional ZO imaging method is that it consider a reflector R as a circular reflector segment Cr placed in the vinicity of reflector R, Cr can be seen as the second order approximation of the reflector. The CRS traveltime surface is the multi-coverage reflection response of the reflector mirror assigned to R.
共反射面元（CommonReflection Surface=CRS）叠加技术是一种全新的、特殊的零偏移距剖面成像方法，CRS迭加理论源于傍轴射线理论，它与普通的零偏移距剖面成像方法的最大区别是它认为地下反射层是由许多个小反射弧段互相叠合组成的，认为来自某反射点附近的一个邻域内的反射信息都可以对该反射点的成像作出贡献，因此对该反射点进行零偏移距成像时就应该聚焦更多的能量参与迭加。

The WCDMA network shares system bandwidth, and is a self-interfering system. The WCDMA network planning should consider the interference control in addition to network coverage. Therefore, it requires more precise propagation models in contrast with the GSM network planning. The WCDMA network supports multiple services, and its support of high-speed services makes the WCDMA network cell coverage smaller and the coverage radius is only hundreds of meters or less. For the dense urban environment, in such small coverage radius, the electric wave propagation paths from the transmitter to the receiver include direct wave, reflective wave on the vertical surface of the building, diffractive waves on the vertical edge of the building, and the diffractive waves on the horizontal edges of the building, and the high-order reflective/diffractive waves (the influence of second-order reflective/diffractive waves is significant), as shown in Figure 1. Therefore, the features and distribution of the buildings are critical to the signal propagation, and affect the receiving signal strength significantly.
WCDMA网络是共享系统带宽的，是一个自干扰系统，因此WCDMA网络规划不仅需要考虑网络覆盖，还要考虑干扰控制，因此相对于GSM网络规划需要更加精确的传播模型；同时WCDMA网络支持多种业务，对高速数据业务的支持使得WCDMA网络小区的覆盖范围较小，半径仅为几百米甚至更小，对于密集城区环境中这样小的半径内，从发射机到接收机的主要电波传播路径包括直射波、在建筑物垂直面上的反射波、在建筑物垂直棱上的衍射波、在建筑物水平棱上的衍射波以及高阶的反射/衍射波(其中二阶反射/衍射波的影响相当大)，如下面图1所示，可见建筑物的特征和分布对信号传播起着关键作用，对接收信号强度有着十分重要的影响。
