Abstract
To solve the problem that linear frequency modulation ( LFM ) pulse compression radar can be affected by the frequency-shifting jamming,a jamming suppression method for initial frequency agility LFM radar based on frequency-shifting detection is presented. The relative position among matched filter refer-ence function,target echo signal and jamming signal in frequency domain is analyzed,and then the charac-ter that the initial frequency among interpulse LFM signal is different can be used. The target echo signal is made to have no pulse compression output through shifting the received signal frequency. So the jamming signal can be identified and suppressed. The anti-jamming performance of the proposed method is analyzed through simulation and the result proves its effectiveness.关键词
