摘　　要：根据水声导航与通信一体化设计需求,分析了水声测距通信一体化的技术体制,对水声测距通信一体化共用同步头做了比较,并对线性调频、双曲线调频、伪随机扩频3种同步方式下的测距误差及误码率进行仿真分析,最后采用伪随机扩频同步头的水声modem实物开展水池测试试验,结果表明,采用9阶的m序扩频码时间分辨率为0.5 ms,水声测距通信一体化的测距和通信性能满足预期。水声测距通信一体化技术研究有助于将来研制小型化的水下多功能一体化水声设备。According to underwater acoustic navigation and communications integration design require-ments, the technical system of underwater acoustic communication integration ranging is analyzed, the shared synchronized heads are compared, the ranging error and error rate of linear FM, hyperbolic FM and pseudo-random spread spectrum synchronous modes are simulated, and finally the test of a physical under-water acoustic modem in which pseudo-random spreading synchronized head is used is tested in a pool. The result shows that 9-order m-sequence spread spectrum code can get 0. 5 ms time resolution,underwa-ter acoustic ranging communication integration ranging and communication performance meets expectations. Ranging study of underwater acoustic communication integration technology helps to develop miniaturized integrated multifunctional underwater acoustic equipment in the future.
