摘要
提出一种结合电磁信号和雷声进行雷电定位的雷电定位系统,定位精度达到米级,可以满足航空航天中心以及特殊区域的雷电定位要求。系统采用在现代信号处理系统中常用的阵列信号处理方法,降低了雷电定位系统对通信的要求,同时也降低了雷电定位系统安装的难度。作者详细阐述了阵列的设计方法以及入射角的估计算法,并提出了传感器的改进方案,根据新方案设计的传感器工作时间少、耗能少、故障率低。
A lightning strike location system is put forward which locates the lightning strike by combining electromagnetic signals and the thunderclap, its location accurate is within a few meters, so the presented lightning strike location system can meet the need of aviation and space center. In this system the array signal processing method often used in modern signal processing systems is applied by which the requirements of lightning strike system to communication are reduced, at the same time the difficulty in the installation of lightning strike location system is also reduced. The estimation algorithm of the angle of incidence and the design method of the array are expounded, the improving project of the sensors are given. The advantages of the sensors designed by improving project are high response speed, low energy consumption and low failure rate.
