This article analyzes the time domain and spectral characteristics of space electromagnetic signal. A method is proposed for constructing the space electromagnetic signal time-domain waveform according to radar equip- ment. Frequency spectrum of signals is analyzed to obtain the power size of detection point, which is helpful for us to analyze the space electromagnetic intensity distribution of complicated battlefield condition. Finally, simulation and detailed experimental analysis verify the correctness and effectiveness of the proposed method.
