摘要
针对传统舰载雷达标校方法的不足,为提高标校效率和精度,提出了一种基于无人机和差分GPS的舰载雷达动态标校方法。文中介绍了该方法的系统方案和标校的基本流程,给出了舰船姿态测量方案和真值获取方法,推导了舰载雷达常用坐标系之间的转换关系,最后讨论了数据同步匹配和标校误差的动态处理方法,形成了系统的标校理论。研究表明,该方法具有标校精度高、通用性好、灵活性高、实施成本低等优点。
Aimed at the insufficient of traditional calibration method for shipboard radar, a dynamic method of shipboard radar based on unmanned aerial vehicle and differential GPS is proposed to improve the efficiency and accuracy of calibration. The system scheme and the basic flow of this method are introduced. The ship attitude measurement scheme and the true values acquisition way are provided. The transformational relation of common coordinate system for shipboard radar is deduced, finally the ways to ensure date synchronization matching and the dynamic processing method of calibration errors are discussed, then the normative theory is formed. The study indicates that the method has many advantages, such as high calibration accuracy, good universality, good flexibility and low implementation.
