Research on real-time spectrum analysis technology

In order to realize the continuous spectrum monitoring of space environment, this paper mainly studies the broadband real-time spectrum analysis technology based on parallel processing architecture, and makes in-depth analysis of the two key technologies, multi-channel parallel FFT technology and digital fluorescence display technology, and uses FPGA devices to realize and verify the above two key technologies. The results show that, using parallel FFT processing technology, the spectrum of each passband can fully cover the whole signal bandwidth, there is no observation blind area, it can be real-time spectrum monitoring of 600MHz bandwidth range, and the digital fluorescence display technology is used to solve the contradiction between high-speed data stream transmission and display.
