为便于水声定位系统在实验室环境下进行电联调实验,本文利用虚拟仪器集成环境LabVIEW,采用内插拟合算法,设计并开发了可产生高精度多普勒信号的水下目标模拟器。该模拟器可根据需求模拟真实海洋环境中的各种目标信号。仿真结果证明,内插拟合算法适用于任何信号形式,任意变化的的多普勒。实验室电联调及湖试试验结果证明,目标模拟器验证了该算法的正确性,满足用户的需求。
In this paper, in order to accomplish the acoustic positioning system experiment in laboratory. Using virtual instrument integration environment LabVIEW and interpolation fitting algorithm, the underwater target simulator that can produce high-precision Doppler signal is designed and developed. The simulator can simulate the a variety of signals in the real marine environment according to the requirements. The simulation results show that interpolation fitting algorithm applies to any form of signal and any changes in Doppler. The results of experiment in laboratory and test at Lake prove the correctness of the algorithm and the simulator can meet the needs of users.
