英文摘要	For the solar radio observations, scientists usually come cross some strong RFIs (Radio Frequency Interferences) producing some invalid observation data. In the past, we had to give up some badly influence bands. Nowadays, we can decrease the RFIs' influences by using advanced circuits, such as high dynamic range analog receivers, remote gain or attenuation controlling software, high performance ADCs and so on. In this paper, we will introduce a new solar radio observation system in Yunnan observatory's 10 meter solar observation system for 800-975MHz observation band which was given up because of some strong RFIs in the past. This new solar radio observation system can adjust the gain from -25dB to +35dB by remote software through RF(Radio Frequency) and MF (Medium frequency) attenuators. Based on advanced FPGA processor we can achieve high spectral resolution of about 30 KHz/channel and high time resolution of about 34ms. This system can easily improve the capability of old solar radio telescopes for adding abandon bands in.
