低纬度哨声接收装置

低纬度哨声接收装置 THE EQUIPMENT FOR RECEIVING LOW LATITUDE WHISTLERS 保宗悌 Bao Zongdi Chen Songbai Wang Tingzhu first-author 陈松柏 王挺柱 为了克服低纬度哨声观测的困难和研究低纬度哨声与纬度的关系,接收装置采用大面积屏蔽环形天线,无输入变压器的低噪声前置放大器和有源高、低通滤波器。本文对这三部分的原理作了简要的讨论。 In order to overcome the difficulty of observing low latitude whistlers and investigating the latitudinal distribution of these whistlers, a large area screened loop, a low--noise pre--amplifier without input transformer and low--pass and high--pass active filters have been used. The underlying principles are briefly described. 1980-03-01 2021-04-01 3
