摘　　要：论文主要分析了长基线水声定位系统的原理,提出了一种新型的合作信标信号;分析了Gold编码信号的产生原理及相关性,并通过理论仿真分析了不同体制Gold编码信号的信号检测概率及测时精度,同时在隐蔽性方面与CW信号进行了对比;通过海上试验,验证了Gold编码信号的可行性。This paper mainly analyzes the principle of long baseline acoustic positioning system,and proposes a new coorperative beacon signal. The production principle and correlation detection characteistics of Gold code signal are analyzed,and the detection probability and tine measuring accuracy of Gold code signal of different systems are analyzed by theoretical simulation. At same time, it is compared with CW signal in terms of concealment. Through sea trials, the feasibility of the Gold coded signal is verified.
