| 摘 要： | 我们成功地进行了超高频闪电方向探测器的试验。三个接收天线(接收闪电放电辐射的超高频脉冲)分别放在一个垂直边长为120米的直角等腰三角形的顶点,由到达天线的时间差来计算接收到的闪电脉冲的方向。用两个分辨率为10毫微秒的时间间隔测定器测量时间差,并用数字打印机来记录测量结果。本文叙述了仪器结构和在甘肃平凉进行的初步观测结果,并指出,观测结果与雷达资料相比是相当一致的。

| Abstract: | A VHF Lightning direction-finder has been successfully tested. The three antennas which receive VHF impulses emitted by a lightning discharge are placed on the vertices of a right-angled isosceles triangle with perpendicular sides 120 meters in length. The direction of arrival of received VHF impulses is calculated from the differences in the time of arrival at the antennas. The time-interval measurements are made with two high-resolution (10 nsec) digital time-interval counters along with a digital printer to record the data. The paper discribes the construction of the instrument and the preliminary results of the observations. conducted in Pingliang, Gansu. The results of observation are compared with radar data and show good agreement. |
