针对航母起降引导系统岸基标校真值测量问题进行研究，提出一种基于着舰引导雷达/中线电视测量数据融合的目标定位算法。首先，考虑到起降引导系统相关设备测量频率不一致，且不同位置船体姿态不同、测量坐标系不统一的问题，进行时间取齐和空间转换，统一转换至理想着舰点坐标系下进行处理；接着推导各设备测量误差的传递模型；最后在新获得的误差方差基础上采用加权平均法将着舰引导雷达和中线电视的测角信息进行融合，并给出最终目标位置估计结果。仿真结果表明：该方法在着舰引导雷达和中线电视性能良好的情况下具备较高的定位精度。
The true value measurement problem is researched against the background of the shore base calibration of aircraft carrier landing system, Based on Fusion of Landing Guidance Radar and Centerline Camera,a target location algorithm is proposed.Firstly,considering the equipments of the system measured the target in different frequency, the carrier movement and the coordinate systems are consistend simultaneously,the paper unified the time and space.Secondly,the transer model was derived for each device measurement error.At last,on the basis of the variance of the error acquired above-mentioned,the angle information of the landing guidance radar and the centerline camera was fused with the weighted average method,then provided the final location results.The simulation rsults show that the method owns high positioning accuracy in the case of well-functioning equipments.
