摘要
水下目标定位与跟踪技术越来越受到了国内外众多学者的重视,由此提出了一种基于浮-信标网络的水下长基线定位系统.采用码分多址技术建立了一种基于浮-信标网络的水声定位系统模型,阐述了定位原理;对定位信标的波形、频率、调制解调方式等关键技术进行了研究;最后,利用MATLAB对实验采集回来的定位数据进行了分析验证,证实了系统模型的正确性.
Underwater target＇s positioning and tracking technology was received increasing attention from foreign and domestic scholars.Based on buoy-beacon network and Code Division Multiple Access（CDMA） technology,an underwater positioning system was put forward.The positioning model was established and some the key technologies were studied separately,such as the waveform adopted,frequency,patterns of modulation and demodulation,etc.The experimental data,which were analyzed by using MATLAB,proved the feasibility of the proposed model.
