Research on Anti-Jamming Performance of Heterogeneous Array Antenna

The anti-jamming ability of heterogeneous array antenna in complex electromagnetic environment is discussed and compared with uniform array and orthogonal dipole array in this paper. A circular heterogeneous array model based on sample matrix inversion (SMI) algorithm is adopted. Simulation experiments verify the ability of the model to receive signals and suppress interference under various conditions. The results show that the array produces significant zero values in the interference direction, while effectively maintaining the signal integrity. In addition, it is particularly noteworthy that the anti-jamming ability of the heterogeneous array using only 8 channels matches that of the orthogonal dipole array using 16 channels, which not only reduces the cost and simplifies the design, but also improves the resource utilization.
