水声同步定位系统在对水声目标进行定位的过程中，定位系统对于目标轨迹的采样率将随目标距离的增加而降低。从而使原始数据减少，并使定位系统的处理能力不能得到有效的利用。长期以来，这个矛盾一直没有得到解决。我们在对这一问题进行深入研究的基础上，发展了一种被称之为“超同步周期”水声定位的新技术，可以大大提高对于远距离水声目标轨迹的采样率。在电路实现过程中，又相应地开发出一种检测定位信号时延值的“余数算法”，并已成功地应用于实际系统。该系统在工作周期为０．４ｓ、目标最大距离为６ｋｍ的情况下，可以有效克服目标“距离模糊”现象，同时对五个目标进行正确定位。在几次湖上和海上试验中，利用“超同步周期”水声定位技术对远距离水声目标进行定位，都取得了令人满意的结果。
Acoustic Synchronization Positioning System In the process of positioning the underwater acoustic target, the sampling rate of the positioning system for the target trajectory will decrease as the target distance increases. Thus reducing the original data, and make the processing power of positioning system can not be effectively used. For a long time, this contradiction has not been solved. Based on the deep research on this issue, we have developed a new technique called “super-synchronous cycle” underwater acoustic localization, which can greatly improve the sampling rate of long-range underwater acoustic target trajectory. In the process of circuit implementation, a “residue algorithm” is also developed to detect the delay value of the positioning signal and has been successfully applied to the actual system. The system can effectively overcome the “ambiguous distance” of the target and correctly locate the five targets under the condition of a duty cycle of 0.4s and a target maximum distance of 6km. In several experiments on the lake and at sea, satisfactory results have been obtained by using “super-synchronous periodic” acoustic localization technology to locate long-range underwater acoustic targets.
