摘要

我们报告了2.8 GHz太阳通量接收器的发展,以监测太阳无线电活动。来自太阳的无线电波被放大、过滤,然后传输到功率计传感器,而不进行频率降频。为了测量太阳通量,设计了噪声源、环境负荷和100℃热负荷的标定方案。该接收器安装在国立无线电研究所所属利川市的1.8米抛物面天线上,每天在白天进行观测。将近7个月的太阳通量与加拿大Penticton的DRAO和日本hiriso太阳观测站的太阳通量进行了比较,最后建立了将观测通量转换为Penticton通量的方程,其精度优于3.2 sfu。

Development of 2.8-GHz Solar Flux Receivers
We report the development of solar flux receivers operating at 2.8 GHz to monitor solar radio activity. Radio waves from the sun are amplified, filtered, and then transmitted to a power meter sensor without frequency down-conversion. To measure solar flux, a calibration scheme is designed with a noise source, an ambient load, and a hot load at 100 ℃. The receiver is attached to a 1.8 m parabolic antenna in Icheon, owned by National Radio Research Agency, and observation is being conducted during day time on a daily basis. We compare the solar fluxes measured for last seven months with solar fluxes obtained by DRAO in Penticton, Canada, and by the Hiraiso solar observatory in Japan, and finally establish equations to convert observed flux to the so-called Penticton flux with an accuracy better than 3.2 sfu.
