深海声道声线图绘制程序，仿真绘制深海声传播图形；并设计了可更改参数的图表及清零功能。(Deepwater channel sound line drawing program, drawing deep sea sound propagation simulation graphics and designed charts and clear function can change the parameters.)

基于keystone算法的距离迁徙校正，用于SAR成像中插值运算(Migration distance keystone correction algorithm for SAR imaging interpolation)

说明：  function [ret,x0,str,ts,xts]=s4(t,x,u,flag) s4 is the M-file description of the SIMULINK system named s4. The block-diagram can be displayed by typing: s4. SYS=s4(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.
