云闪和地闪的波形采集、数据处理及其初步应用
Detecting and Processing Waveform from C-G and Cloud LightingDischarge and It’s Preliminary Application
【摘要】 利用美国进口的闪电定位仪 (LightningDirectionFinder)和日本TCCJ - 2 0 0 0型瞬态波形存储器连接 ,在 5 0 0Hz~ 5 0 0kHz的频段内 ,用 0 .1μs的采样速率和 2 0 4.8μs的记录长度 ,对闪电的电磁辐射信号进行采样 ,数据经过安装在微机上的一块PET -DIO接口卡被微机处理并存储。本文还对一些资料作了初步分析
【Abstract】 A LLP made Direction Finder (DF) was connected properly with type TCCJ-2000 transient converter to record the strength and wave shape of the electromagnetic radiation from lightning flash with sampling time, recording length and bandwidth of 0.1 μs,204.8 μs and 500Hz~500kHz, respectively. Data collected were processed and stored by a PC through an installed inside PET-48DIO board . In addition, a preliminary data analysis was provided.
