摘　　要：为了实现对水下目标的定位,提出一种CW信号与LFM信号组合的水声信号机制,并完成了模拟检测。该信号机制中CW信号用于测距,LFM信号用于测深。一组帧信号与三组行信号组合,共同完成目标定位,并且有效减小误差。仿真结果表明,该信号机制在水声信道中能有效的传输,被检测及实现定位要求。In order to locate the goal underwater, we propose a underwater acoustic signal mechanism combined CW signal and LFM signal, and complete a simulated test. In the signal mechanism CW signals is used for the ranging , LFM signal for sounding. Frame signal combined with three line signals complete the target location , and effectively reduce errors. Simulation results show that the mechanism can effectively transmit signals in underwater acoustic channel , to be detected and to achieve positioning requirements.
