- Abstract
In military wireless communication, analyzing and recognizing the jamming signal to receiver and extracting the jamming parameters to provide information assistance for the total anti-jamming decisions of communication systems is very important to confront the intended jamming. The short-time Fourier transform(STFT) algorithm is proposed to analyze the jamming. Firstly, STFT is performed for the multiplicate regular jamming, and then the 3D time-frequency data is uniformized. Finally, according to the different jamming types in time and frequency domain, the relationship between time and frequency is analyzed and the constant jamming, duration pulse jamming and sweeping jamming are extracted step by step. Theoretical analysis and simulation results show that the distributed searching algorithm can precisely extract the jamming parameters.
