摘　　要：在多传感器对目标进行引导时,传统目标方位角以地理北为方位参考,由于极区经线收敛导致地理北迅速收敛于北极点,进而导致目标方位角的误差增大,无法满足极区舰艇作战指挥系统对目指信息的精度需求,为了克服这一问题,提出建立横向地理北作为方位参考,并在此基础上构建大地主题解算模型以及无迹卡尔曼滤波模型,仿真分析的结果表明,提出的方法能够提高第三方引导下的极区超视距目指信息精度,能够满足极区舰艇作战指挥系统对目指信息的精度需求。When the target is guided by multiple sensors,the traditional target azimuth is represented with the reference of the geographical north,while the geographical north converges in the north pole rapidly due to the convergence of the meridian in arctic region leading to the increase of the error of the target azimuth angle,which is unable to meet the demand information of target indication precision of combat command system of naval ship in arctic region. To overcome this problem,the establishment of horizontal geographic north as a reference is proposed,and on such basis,the geodetic theme solution model and the unscented Kalman filter model are constructed. The results of simulation analysis show that the method can improve the target（ OTH） information accuracy as guided by the third party guidance in the high latitude region; it can satisfy the demand information of target indication precision of combat command system of the naval ship in Arctic region.
