测向交叉定位协同信息远程传输方法研究

摘要

多被动传感器测向交叉定位精度与传感器之间协同信息的传输距离（基线长度）直接相关。被动传感器实施测向交叉定位时的基线长度较短将导致定位精度不高，无法满足武器打击的目指精度要求。针对此问题，提出了基于北斗短报文的测向交叉定位协同信息远程传输方案，并对其技术可行性和实现方法进行了研究。该方案能够极大地延长基线长度，显著提高多被动传感器的测向交叉定位精度。%Positioning accuracy of the bearing-only location system with multiple passive sensors is closely related to the transmission distance(baseline length)of cooperative information between the passive sensors. If the baseline length of the bearing-only location system with multiple passive sensors is short,the positioning accuracy will be too low to meet the requirement of the target indication accuracy for weapon attacking. The cooperative information remote transmission scheme based on the Bei-dou short-message communication isproposed to solve this problem. Its technical feasibility and implementation method is re-searched. The scheme can greatly increase the baseline length,and significantly improve the positioning accuracy for the bearing-only location system with multiple passive sensors.
