In this paper,the principle of complex source point and various analyt-ical methods of complex ray are summarized.Some possible applications ofcomplex ray method to underwater acoustics are proposed,including complexray analysis of directional acoustic fields,complex ray simulation of directivityof acoustic radiator arrays,complex ray transformation of acoustic fields fromnear zone to far zone,as wel1 as theoretical prediction of sonar target strengthby complex ray method.
