Frequency-Space Domain Anti-Jamming Algorithm Assisted with Probability Statistics
Global positioning system (GPS) signal is weak and vulnerable. Using the frequency-domain notching filter cascaded with space domain filter can improve the anti-jamming ability of the GPS receiver. However, when the narrowband jamming falls in the wideband one, it is difficult to detect the narrowband jamming spurs correctly by fast Fourier (FFT) transform. In this paper, the probability statistics algorithm is proposed to help detect narrowband interference location in frequency spectrum. Numerical results show that the proposed algorithm performs well.
