摘要
In this paper, the principle of complex source point and various analytical methods of complex ray are summarized. Some possible applications of complex ray method to underwater acoustics are proposed, including complex ray analysis of directional acoustic fields, complex ray simulation of directivity of acoustic radiator arrays, complex ray transformation of acoustic fields from near zone to far zone, as well as theoretical prediction of sonar target strength by complex ray method.
