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。
Ground-penetrating radar network can achieve their complementary advantages, especially to enhance the detection and tracking ability of low-altitude targets, but the premise is to realize the registration of moving space-based radar and stationary ground-based radar. In order to be close to reality, an observational model of space-time radar asynchronous variable data rate was established under the coordinate system of WGS-84 (World Geodetic System), and time-based registration of ground-based observations was performed by interpolation and extrapolation. Based on this, Least squares registration algorithm for spatial registration. Simulation results show the effectiveness and feasibility of the algorithm.
