摘要：

本文介绍了成像式宇宙噪声接收机技术和数据分析方法,通过对南极中山站成像式宇宙噪声接收机在2003年10月底太阳风暴期间的观测数据进行分析,得到了相应的极区电离层的吸收效应,它们主要是强度为2. 7dB的宇宙噪声突然吸收和强度高达31dB持续4d的极盖吸收。

Abstract:

The technique and data analysis of imaging riometer are presented in this paper. Some absorption effects in polar ionosphere were obtained by means of the imaging riometer at Zhongshan station during solar storms at the end of October 2003. The main features were: a sudden cosmic noise absorption (SCNA) with 2.7 dB and a polar cap absorption (PCA) lasting about 4 days with a peak up to 31 dB.
