摘　　要：本文介绍复源点射线技术原理,概述各种复射线分析方法,并举例说明这种方法在水声技术中一些可能的应用,包括指向性声场的复射线分析,声辐射器阵列方向性的复射线模拟,近区和远区声场的复射线变换,以及声呐目标强度的复射线理论预估等。In this paper, the principle of complex source point and various analytical methods of complex ray are summarized. Some possible applications of this 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 evaluation of sonar target strength by complex ray method.
