A new digital spectrometer for low frequency solar radio observation based on FPGA

摘要：

In this paper, we introduce a new digital spectrometer for low frequency solar radio observation based on FPGA. The single ADCs sampling rate is at 204.8Msps (Million sampling per second), so the input bandwidth of this spectrometer can reach 204.8MHz based on Nyquist sampling theorist1. The input dynamic range of this spectrometer can achieve nearly 72dBm because of multi-bit sampling. In the same time. this spectrometers spectral resolution can be set O.2MHz/channel, 0.4MHz/channel and 0.8MHz/channel by program, and time resolution can also be set 2ms, 5ms and 1Oms by program.
