Verification and analysis of electromagnetic environment based on Simulink

In recent years, the battlefield electromagnetic environment is becoming more and more complex and its quantitative token becomes a serious problem that need to be solved urgently. In this paper, the average power spectral density (APSD) is proposed as a parameter to quantitatively analyze the electromagnetic environment in frequency domain, and the pulse Doppler radar simulation system based on Simulink has been built to verify the effectiveness of the proposed parameter. The verification shows that the APSD can be used as an index to describe the electromagnetic environment of the blanketing jamming under clutter or noise.
