Design and implementation of Beidou anti-jamming antenna

This paper introduces the realization method of Beidou anti-jamming antenna hardware and software, theory analysis and MATLAB simulation of antenna array and adaptive algorithm. The space time joint anti-jamming algorithm based on the linear constraint minimum variance criterion is adopted as the core of the anti-jamming processor. It is designed and implemented successfully. the anti-jamming ability of the antenna is tested and verified. The antenna has the capability of resisting single jam 75 dB and resisting three jam 60 dB. Finally, the difference between theoretical simulation and practical implementation is analyzed, and future work is prospected.
