摘要
A new method is proposed according to the features that the frequency difference of linear frequency modulated (LFM) signal is independent to time. The LFM signal is multiplied by its self-delayed one to get the linear relationship between them and then the LFM signal frequency is shifted. This method is adaptive to chirp-rate-agility or frequency-diversity. One of the jammer structures which can realize the method is given and the calculation formulas describing the gain of the jamming signal after match filter is deduced. The simulation result is consistent with the one obtained by theoretical analysis.
