| Abstract: |
| A genetic algorithm(GA) assisted beamforming algorithm is applied to a 2-dimensional circular antenna array, and its performance of pattern nulling is studied. An improved binary code method is also proposed, which introduces several parameters to conveniently control the solution precision and search space. The simulation results show that the algorithm can make the antenna array track the signal and efficiently suppress several strong interferences at the same time. The model introduced in this paper is applicable to the problem of anti-jamming in satellite communications. |
