This report describes a new method,the self-searching method,tofind eigenrays in an ocean where there is a three-dimensional sound speedperturbation blob on a uniform sound speed background.Compared with thetraditional shooting method,this method can reduce the number of ray calcula-tions by about two orders of magnitude,and an eigenray can be found by com-puter program without manual intervention.
