磁带测量雷电流幅值的新装置

The New Divice for Measuring Lighting Current Using Magnetic Tape

提出一种新的锁定时标方法,通过读出磁带基准信号抹长来测量雷电流幅值.误差分析及实测量试验表明,该测量方法准确、可靠,误差小于±3％。

This paper presents a kind of the base lock and compnter aided method and the device for measuring the length of signal pre-recordcrd on the tape and erased by the lightnring current the total error is smaller than ±3%.
