A New Method to Observe Radio Astronomy Signal: Centimeter-Decimeter Spectral Line——Based on High Performance Integrated Circuit

Spectral line observation plays an important role in astronomy. High spectral resolution can bring much convenience to observers in exploring planet details. But for high-frequency observation, it is very difficult for the traditional sampling method to achieve high spectral resolution. In this article, a new method has been proposed. Using high performance integrated circuit to observe radio astronomy signal in centimeter-decimeter spectral line, this method overcomes those disadvantages of its traditional counterpart and achieves a higher spectral resolution with a lower sampling bandwidth. It consists of a complete set of collection, processing and storage solutions. Firstly, high-frequency signal is processed by the analog down converter, then the low-frequency signal is transmitted to the upper computer software for FFT and integral processing; finally, the signal is saved in file format as required. In this platform, parameters for data collection are given by the observer through upper computer software.
