靶场脉冲测量雷达组网技术

针对目前靶场脉冲测量雷达链式工作方式易受多站信号干扰丢失目标的缺点,提出了一种靶场脉冲测量雷达组网的工作方式。文中阐述了组网工作方式的原理和优点以及需要解决的关键问题,并对靶场雷达组网进行仿真,分析了不同基线长度下定位精度几何分布情况。结果表明两站法线方向测量精度较低,长基线精度优于短基线。并且根据目标飞行轨迹,合适的雷达站点位置,可以有效地提高测量精度和任务可靠性,同时实现数据共享,资源合理配置、集中管理,避免多任务冲突。靶场脉冲测量雷达组网的工作方式对提高靶场测控系统的性能具有重要的意义。

Netting Technology of Shooting Range for Pulse Radar

Because the present pulse radar working in chain mode in shooting range is susceptible to signal interferences from multiple radar stations, a kind of network mode of pulse radar is proposed in shooting range. The principle, advantages and key problems need to be solved of the network mode is expounded. In this paper, the network mode is simulated, and the geometric dilution of precision(GDOP) of different baseline length is analyzed. The results show that the measurement precision of the normal direction between two stations is low, and the precision of the long baseline is better than that of short baseline. According to the target trajectory, suitable radar sites location, the measurement precision and the reliability of the tasks can be effectively improved. At the same time, data sharing, reasonable configuration and centralized management of resources can be realized for avoiding the conflict between multiple tasks. The network mode of pulse radar is the significance to improve the performance of the measurement and control system in shooting range.
