舰艇协同防空时间同步误差对目标定位的影响

Analysis on the Influence of Time Synchronization Error on Target Location Under Multi-platform Synergistic Air Defense Mode of Surface Ship

多平台协同防空可以获得比单平台防空更高的效率,但是其定位精度也受到各平台时间同步误差的影响。文中基于水面舰艇多平台协同防空模式下,时间同步误差对整个防空系统效率的影响,分析了协同防空系统对时间同步系统的需求,讨论了现阶段时间同步系统的建立技术,最后针对多平台协同防空时的辅助跟踪和交叉定位两种模式,分别建立了目标定位精度和时间同步误差之间的数学模型。

Multi-platform cooperative air defense can achieve higher efficiency than single platform,but its positioning accuracy is also affected by the time synchronization error.In this paper,based on the surface ship multi-platform cooperative air defense mode,the effect of time synchronization error on the efficiency of the whole air defense system is presented,the demand of the cooperative air defense system for time-synchronization system is analyzed,the establishment of time-synchronization system at present stage is discussed.Finally,aiming at two modes of assistant tracking and cross location in multiplatform copperative air defense,the mathematic models between target positioning accuracy and time synchronization error are established.
