This implementation is finished open with ITUP1546 to view gui interface. Read the ITU P.1546 propagation document to understand how to measure you input values. This was created from ITU p.1456-3 Minor issues corrected -warm sea paths

声线绘制程序，要求在声线不碰海底、海面的情况下，根据所给的任意大洋声速剖面、声源深度和声线传播的水平距离，画出出射角从-10°到10°的20条声线在大洋声道传播的情况-Acoustic line drawing program, not touch the seabed under the conditions of the sea, according to any oceanic sound velocity profile, the sound source depth harmonies

Okumura analyzed path-loss characteristics based on a large amount of experimental data collected around Tokyo, Japan. He selected propagation path conditions and obtained the average path-loss curves under flat urban areas. Then he applied several c

短波在海面传播特性，传播距离在4000km之内-Short wave propagation characteristics in the sea, the propagation distance within 4000km

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.
