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 low latitude whistler observation and study the relationship between low latitude whistle and latitude, the receiving device uses large area shielded loop antenna, low noise preamplifier without input transformer and active high and low pass filters. This article briefly discusses the principles of these three parts.
