摘　　要：雷达时空配准是航管系统中面临的首要问题,是多源监视数据融合处理的第一步,直接关系到航迹效果,配准精度直接影响飞行安全。针对全局参数不能校正局部非Gauss偏移的问题,给出了一种基于地图投影的空间坐标投影转换方法;在时间配准上,将待处理目标在统一时间上进行插值处理;在空间配准上,通过偏差估计理论导出分区下的校准值计算方法;并给出了一种校准值曲面的计算方式。最后用实测的三部雷达数据进行了验证,与GLS校准算法相比,距离偏差精度提升了9%~29%。Radar spatial-temporal registration is a primary step of air traffic control automation systems(ATCS),as the first step in multi-source information fusion,directly impacting trajectory accuracy,where registration accuracy critically affects flight safety.For the global parameters cannot correct the local non-Gauss offset,this paper describes a spatial coordinate projection conversion method based on projection.The measurements is processed at a uniform time by interpolation for time alignment.The method of calibration under partitioning is derived from the theory of bias estimation for space alignment.A method of the calibration surface is given.Finally,this paper is validated with three radar data from real measurements,and the distance deviation accuracy is improved by 9%~29%compared with the Generalized Least Squares calibration.
