Abstract: The accurate measurement of radar high pulse field is of great significance to the study of the characteristics of electromagnetic environment and electromagnetic safety of the equipment. For radar high pulse field, the typical used frequency-domain measurement method is time-consuming, and the measurement results are related to the resolution bandwidth setting. The inappropriate setting may lead to wrong results. Based on the analysis of the time-frequency characteristic of pulse signal and the research on the measuring principle of oscilloscope and field intensity probe, this paper puts forward a fast measuring method of peak and average field intensity based on oscilloscope and field intensity probe. The problem of fast measurement of high power radar pulse near field distribution is solved, and the boundary conditions of field intensity probe in the combined measurement method are given. The experimental results show that the error of the combined measurement method of field intensity probe and oscilloscope is less than 1 dB and can be verified mutually.
