摘　　要：空、地多雷达配准是空地一体化预警的前提。通过建立空中运动雷达与地面静止雷达的配准模型,以最大似然算法为基础,导出其空间系统误差配准参数及目标运动状态估计的具体公式,并对系统误差估计值的卡拉美-罗界进行了讨论。仿真结果表明,该算法具有较快的迭代收敛速度和较好的配准效果。Multi-radar registration with airborne radar and ground radar is the premise of air-ground integration early warning. A registration model for airborne moving radar and ground static radar is built Based on maximum likelihood algorithm, the formulae about the registration and target state estimation were derived. The Cramer Rao lower bound of the system estimation error is discussed. The simulation results show that the algorithm has rapid iterative convergence speed and fine registration effect.
