Abstract
In order to solve the problem that the simple jamming signal can not interfere the pulse compression radar effectively,a smart jamming signal based on the linear frequency modulation (LFM) waveform is proposed.According to the design principle of LFM waveform,the jamming signal of smart jamming was established after intermittently sampling and transmitting the wave form signal.The time-frequency distribution of smart jamming under different duty ratio was simulated and compared by setting the intermittent sampling duty ratio to 0.2 and 0.5 respectively,and the results of time-frequency joint distribution of smart jamming were further obtained when being in oppression jamming and deception jamming condition respectively.The simulation results show that deception jamming effectiveness will be appeared when duty ratio is larger and oppression jamming effectiveness will be appeared when duty ratio is smaller.That is,the smart jamming will have strong flexibility and pertinence by matching the radar waveform.关键词
