Abstract

Based on an old decimetric solar radio spectrometer working in the frequency range of 625-1500 MHz of the Yunnan Astronomical Observatories (YNAO) during the last solar cycle, we designed a fully digital Fast Fourier Transform (FFT) spectrometer to upgrade the old one. The new digital spectrometer has the spectral resolution of 200 kHz, much higher than the old one (about 1.3 MHz). In addition, we also established a new metric solar radio telescope working in the frequency range of 70-700 MHz located at the Fuxian Solar Observatory of YNAO, deploying the same type of the digital FFT spectrometer. The two instruments have begun to operate in a daily survey mode since September 2009 and March 2012, respectively, and many solar radio bursts have been observed. In these events, various types of decimetric and metric fine structures with fairly meticulous spectral features were recognized. These features were never resolved in previous observation and studies. We have introduced these two instruments with their detailed technological components, as well as a set of observational data obtained during the first-light of the instruments. The information revealed by these data can improve our knowledge and understanding of the physics of the energy conversion, particle acceleration and transportation during the solar eruption.
