摘要
空地雷达组网能实现二者的优势互补,特别是增强低空目标的探测跟踪能力,但其前提是实现运动的空基雷达和静止的地基雷达的配准。为贴近实际,在WGS-84(World Geodetic System)坐标系下建立空地雷达异步变数据率观测模型,采用内插外推的方法对空地观测进行时间配准,在此基础上导出适合工程应用的最小二乘配准算法进行空间配准。仿真结果表明了该算法的有效性和可实现性。
The ability to detect low altitude targets is much enhanced by netting of airborne and ground-based radars.The premise is registration for moving airborne radar and static ground-based radars.An asynchronous and varying rate measurement model based on WGS-84 coordinate for airborne radar and ground-based radars is built.Interpolation and extrapolation algorithm is used to implement time registration.Least square algorithm fit for project was deduced for space registration in WGS-84 coordinate system.The results of simulation demonstrate the method is effective and realistic.
