In order to use the whole pulse sampling sectional stack jamming method more accurately and flexibly, its jamming characteristics are analyzed. Firstly, the action process of jamming in the matched filter of LFM pulse compression radar is deduced, and the jamming characteristics of jamming to the matched filter are analyzed; Then, according to the jamming characteristic analysis conclusion, the jamming characteristic analysis conclusion is verified by means of qualitative analysis of simulation experiment, quantitative analysis of hardware in the loop experiment and analysis of jamming experiment effect of radar system. The experimental results show that the effect of interference is consistent with the analysis conclusion of interference characteristics. Some supports for the construction of corresponding interference scene and the design of interference sequence in electromagnetic environment simulation are provided by the analysis conclusion of this characteristic.
