A Kind of Tortuosity Lightning Channel Model and Calculation of Its Radiated Fields

摘要

In order to precisely describe the radiated fields of lightning channel, and model the high frequency spectrum, based on the Transmission-Line model of lightning current, the model of a tortuous lightning channel is formulated, and conception of effective observable distance of lightning channel's radiated field is proposed. The effects of current segment's tilt angle, current propagating velocity and observable distance on radiated fields are researched.
