Abstract

In order to monitor the electromagnetic environment of the test site, this paper mainly studies the real-time spectrum analysis of the 1 GHz instantaneous bandwidth electromagnetic signal. The time slice is used to divide the continuous time into 8 groups. Each group of time slice performs multi-multiplexing parallel FFT on the electromagnetic signal, and real-time spectrum analysis is performed using spectrum statistics and digital phosphor display at the same time. Experiments show that the system can continuously monitor the electromagnetic signal with an instantaneous bandwidth of 1 GHz. Real-time spectrum statistics technology reduces the sampling rate from 2 500 MB/s to less than 1 MB/s, which greatly reduces the transmission pressure of output data and expands the application environment of the system while satisfying the real-time spectrum monitoring and analysis in complex electromagnetic environment.

Keywords
