摘要
为提高舰艇编队多站无源时差定位(TDOA)精度,必须解决水面舰艇平台间高精度的测距和时间同步问题。研究分析了几种时间同步技术,提出一种适用于舰艇编队的改进型双向比对时间同步控制技术,通过仿真实验得到舰艇间时间同步误差在7.5ns以内,测距精度在2.5m内。
In order to improve the accuracy of multi-station passive time difference of arrival （TDOA） location of ship formations,the problems such as the high precision range-finding and the time synchronization among ship platforms must be solved. This paper studies and analyzes several time synchronization technologies;puts forward an improved two-way time transfer （TWTT） syn- chronization control technology,which is suitable for ship formation. The time synchronization er ror among the ship formations can be less than 7.5 ns and the range-finding accuracy can be less than 2.5 m through the simulation experiments.
