这个主要是讲解声波方程数值模拟的，实现了无反射波动正演，可应用与非均匀介质有两种吸收边界条件-This is mainly to explain the numerical simulation of acoustic wave equation, to achieve a non-reflective wave forward, can be applied with non-uniform medium, there are two absorbing boundary conditions

主控方程为一维线化Euler方程，采用无反射边界条件，时间推进采用前差格式，内部流场计算采用中心差分格式。-govern equation for the one-dimensional linearized Euler equations, the use of non-reflective boundary conditions, time advancing front differential format, the internal flow field is calculated u

fortran代码，读雷达基数据,格式为敏视达SA，类型为反射率因子。将其读入内存。读者可以自行后续处理。-fortran code,read radar base data,data type is reflective rate.
