| Description | Journal: Journal of Physics: Conference Series To inhibit interference, the conventional space-time adaptive processing technology can form nulling at both the interference coming angle and the interference frequency, inhibiting the interference in the development of satellite navigation anti-jamming technology. When the frequency of the signal source is equal or similar to the central frequency of the interference source and they are adjacent in the spatial domain, the desired signal will be suppressed in the traditional algorithms, which will lead to the decrease of the output signal-to-interference-noise ratio (SINR).To overcome this issue, a space-time joint anti-interference algorithm based on planar array steering is proposed in this paper. Specifically, the plane array steering is adjusted by calculating the spatial correlation coefficient of the desired signal and the interference signal. Simulation results show that the proposed algorithm can increase the output SINR by about 10dB under the same frequency, and the anti-interference ability of the system is enhanced. |
