Especially in military affairs, it is the vital part in military operations. Short-wave communication is attractive because only little power and proper expenditure is needed when it is used for long distance communication. For this valuable trait, many country have expanded the area of short-wave communication's research, thus there has become more and more new-model communication system.

短波通信之所以能吸引用户用它传递信息，最基本的原因是由于进行远距离通信时，仅需要不大的发射功率和适中的设备费用，这一宝贵的优点，使得世界各国近年来加紧了短波通信的研究，出现了各种新型的短波通信系统。

Like the case of the VTI, only the nonhyperbolic traveltime data of the P-wave are not sufficient to retrieve the three parameters V_(p0),εandδ, suggesting that the inversion can be performed by using multiazimuth nonhyperbolic (long-spread) P-wave reflection traveltime data, and vertical velocity from check shot and drill or log well data.

对于VTI介质，P波反射由V_(p0)、ε和δ三个参数来描述，在其它资料给出垂直速度V_(p0的前提条件下，ε和δ两个参数可由近偏移距NMO速度和远偏移距四次时差系数(A_4)两个条件来约束反演，那么反演解是唯一的。

Based on the theory proposed by Alkhalifah, that is the reflection wave is determined by normal moveout velocity V of short-spread and anisotropic parameter η under the condition of long-spread data of vertical and lateral isotropic media and non-hyperbolic curve, a method for long-spread data velocity analysis is studied. A 2 step scanning method is used for the hyperbolic and dual parameter scanning of long-spread data.
