关键词Digital Backend Radio Astronomy Under-sampling Technology Adcintroduction
摘要For traditional radio astronomy instruments, we usually achieve the wide bandwidth by using the single high speed sampling rate analogy to digital convertor (ADC). But this method can lead some problems for processing, such as radio frequency interference (RFI), data transmission and so on. Take advantage of ADCs' wide input bandwidth, we can also sample observation signals with wide bandwidth using comparatively low speed sampling rate. In this paper, we introduce the under-sampling technology, and then analyze some applications in radio astronomy. Finally, we introduce a new digital spectrometer based on this technology for solar radio observation whose core ADC is AD9430.
