摘　　要：本文对收发分置情况下,某潜艇模型的声散射特性进行了理论分析和实验研究。在声源、目标和接收机之间呈复杂的三角形关系条件下,找到了目标强度与入射角、分置角之间的关系。通过理论计算和水地测试,验证了理论的正确性。该研究成果可直接应用于收发分置的双基地或多基地水声探测系统。Abstract: Under the situation of separated source and receiver, theoretical analysis and experimental research on acoustic scattering properties of some submarine model are made in this paper. When the configuration of source, target and receiver has complicated triangular relationship, the relationship among target strength, incidence angle and bistatic angle is obtained. The correctness of this theory is verified by theoretical calculation and tank experiment. The research results can be directly used in bistatic or multistatic underwater acoustic detection systems.
