主 题:Underwater acoustics
摘 要:The Ludwig s uniform asymptotic developments are considered for description of underwater acoustical channels. The integral which gives the field is formulated with help of approached analytical expressions of the acoustical geometrical solution. Complex rays are taken into account in the shadow regions. A method of computation for this integral is presented here.
